Foreword

2009 was a year of training and education!

The economic measures taken by the German Federal Government have had a positive effect on this development; it was important to prepare those ones working short time for future tasks as best as possible. Small and medium sized companies were grateful to get this opportunity thus being able to increase their competitiveness. The GSI adapted to these needs by putting aside their own aims in favour of customer demands.

Furthermore, the business year was characterized by two central events:

•the10thanniversaryoftheGSIand •thefairSchweißen und Schneiden (Welding and Cutting) in Essen.

The anniversary gave rise to all employees of the GSI, of the cooperating institutes as well of the foreign companies to recapitulate the past years and express their team spirit.

The communicative and future directing performance of the GSI at the fair was distinc-tively oriented at the demands of the customers. All systems available worldwide for com-puter based education of welders were presented and the role of the GSI as the market leader of education was emphasized by this.

At the end of a year of commitment and a lot of work the annual accounts have formed a lot of options for the future. The operative business, however, to be expected for 2010 is difficult to estimate.

The economic changes will have an influence. It is certain, however, that a technical further development of the products also requires well educated personnel in 2010. To perform this at a high quality will be our aim number one for the next year.

General Development of the Business

Overall Estimate

Since the GSI was founded 10 years ago it has developed as an economically stable and efficient company. The reasons for continuous growth and sales increase were mainly the investment of new products, of the design of buildings and business but also the foresigh-ted qualification of the employees.

During the last three years it has been necessary to adapt the new company structures to new requirements and to increase efficiency even more. Characteristic values such as the turnover per capita are proof of the success of the concept.

The characteristics of quality of the GSI are very complex to evaluate. The assistance of participants, however, has been comparably easy to evaluate. The question concerning an adequate, compact and state-of-the-art content is much more demanding. Hence, the future business policy of the GSI as a provider of specific services on the field of joining and allied processes will direct the way ahead.

Profits and Financial Situation

As in the previous years the GSI could further increase its turnover in 2009, too, which lead to a positive influence on the result. All this has contributed to further secure the programs of investment decided upon in the years before. The funds for the planned construction projects at the locations of Gelsen-kirchen and Wilhelmshaven are available. In addition to this, preparations for new projects may start.

Investments

In the business year 2009 a total of € 5.1 million (2008: € 3.4 million) was invested for im-proving the teaching facilities as well as for the creation of new education facilities in Wil-helmshaven and in China. For the current business year 2010 a regular investment volume of € 2.5 million has been planned. Moreover, some longer-termed investment projects of a volume of € 6.5 million are shortly before and just being realized. Pursuant to the non-profit purpose of the company the media for modernizing the exis-ting facilities are used for the creation of new education facilities as well as for the support of education and training in welding and allied processes such as joining, cutting and coating of metallic and non-metallic materials, and in materials testing.

Particulars

As from 01. 07. 2009 Mr. Dipl.-Ing. Christian Ahrens has been head of the newly created foreign business branch of the GSI. The foreign business branch has a combined func-tion: it directs the foreign institutes of the GSI in Poland, the Czech Republic, Turkey and Egypt supporting their activities in cooperation with the subject sections (Fachressorts): In addition to this, foreign projects are assisted worldwide. Mr. Ahrens is supported by Dr.-Ing. Hans-Georg Groß who is engaged in the region of eastern Europe/GUS. At the same time Mr. Ahrens is the managing director of the GSI Kunshan, which was founded in China in 2009. His experience gained through many years of participation in the IIW, International Institute of Welding, and his current activity as the chairman of the IAB Group A will be useful for his new task.

Prof. Dr. Dietmar Paulinus was nominated head of the section Education and Training. As from 01.07.2009 he has taken over this task supplementary to his activities as head of the SLV Berlin-Brandenburg from Mr. Dipl.-Ing. Ahrens.

Mr. Dipl.-Ing. Jörg Mährlein was nominated deputy head of the SLV-Duisburg. Mr. Mähr-lein is taking over this function supplementary to his activities as head of the department QS (Quality Assurance). In addition, he represents the GSI mbH in international committees such as the chairman of the Sector Group 17 within the GNB Group of Notified Bodies.

In the business year 2009 the number of employees was increased by approx. 10 %. All fields of business were concerned by the increased demand in personnel with a focus being in the area of education and training.

Training and Education

With the new presentation of the GSI in the internet made available at the beginning of 2009 the possibilities of getting information on special services offered by the GSI have further improved. For the first time, the whole range of performances of education and training can be searched for according to its latest state. Each topic informs about the dates and locations of the training courses.

A special online field for conferences advertises events taking place nationwide. Internati-onal conferences with an own domain may also be developed as a platform. The reactions of the customers very distinctively show that this initiative has also gained international reputation while being used a lot. Of course, the internet presentation of the GSI is availa-ble in German and in English.

Distance learning courses are still trendy. The existing range of education such as the edu-cation as welding engineer is continuously supplemented and extended with particular focus on the training courses on the field of non-destructive testing. By the fair Schweißen und Schneiden 2009 in Essen this offer was presented to a broad public for the first time.

Development of the distance learning courses since their incorporation to the range of education

Not only new training is used but in a phase of intensive qualification also the proven ones were used by the customers. It´s nice to report that the demand to educate welding instructors and welding specialists has increased. Both of them are of importance for the production process.

In special fields of education such as resistance welding and cold joining the crisis of the automotive industry, however, could be distinctively noted. The number of training cour-ses performed on a high quality level in the previous year has significantly decreased. After a phase of consolidation in automotive construction an increased demand in the following years is very probable.

Research and Development

The general situation on the world markets has also an influence on research. The business programs of the Federal Republic of Germany have had a positive influence within the GSI and their cooperating institutes. Supporting programs such as the ZIM (Central innovation program of the medium-sized companies) offer an ideal support for small and medium-sized companies permitting to enter new paths of research coopera-tion with attractive financing conditions. The extension of these programs to the whole Federal Republic of Germany has also given larger companies the possibility to access as well as it has stimulated the demand. The direct and project related cooperation with industry has distinctively shown which branches were considerably affected by the economic crisis. Therefore, the cooperation with the automotive industry has significantly been reduced which could be partly com-pensated by branches less affected such as the field of energy production. Often it is decisive for the interest of the companies whether the field researched is a new one. This has become particularly distinctive with the works on magnetic pulse welding or the laser GMA hybrid welding technology.For the next few years an increased research on the field of joining technology is very probable since many companies will have new products after the crisis wishing to secure them by new joining techniques. Here, the wide range of services, particularly the re-search competence of the GSI is important.

Quality Assurance

Building supervision - Execution of welding and corrosion protection The building supervision projects of the GSI was concentrating on the areas of bridge construction, power plants and steel structural engineering. Among them were projects having a scope of performance of a considerable amount for a company like the GSI re-quiring international cooperation with the foreign cooperating institutes. Hence, some advantages like a regional rendering of services and the reduction of traveling costs were the result.Reference objects with supranational character are also important to be stated such as the new construction of the airport BBI (Berlin-Brandenburg-International) in Berlin-Schönefeld. For this „capital airport“ steel structures were inspected and supervised on their professional welding execution both in the manufacturing works and during the assembly on major building sites.

Certification of welding and adhesive bonding companies Contrary to the general trend the certification of welding companies has turned out to be a stable business process. Beside of the certifications for companies in metal and rail vehicle construction traditionally represented to a large extent, first certifications of adhe-sive bonding companies in rail vehicle engineering in accordance with 6701-2 were parti-cularly remarkable. Due to the expiration of the transition period until the introduction of the standard at the end of 2009 the demand of certifications has risen as expected.

In whole Europe the standard EN 15085-2 has been introduced. Manufacturer certification boards, national safety agencies, rail vehicle manufacturing and repair shops as well as operators of rail vehicles agree that the benefit of the standard will be given not before it is overall agreed and interpreted. Therefore, all those concerned have formed an alliance in the association of the ECWRV – European Committee for Welding of Railway Vehicle. The work of this committee is based on the initiative of the GSI as well as the internet re-gister „EN 15085“ and its internationalization.

Material Testing

The GSI has a German wide net of accredited material testing laboratories. Here, welder examinations and welding procedure qualification tests are performed on customer de-mand within the scope of education and training. Moreover, the laboratories with their test performance and evaluations are a firm constitu-ent of research projects. Often it is the direct feedback from the laboratories which serves to optimize the process parameters. This is particularly valid for metallurgically deman-ding materials. When monitoring construction products such as reinforced concrete, the services of the testing laboratories are used

Central Offices

Within the GSI the central office have taken over a trade related coordinating function while using the resources of the branches and sectors and orienting towards the market demands. Within the branch they join the elements such as qualification for customers and own personnel, certification, standardization, research and product development. The GSI has central offices for the branches of metal construction, rail vehicle construction, military engineering, pressurized vessels, pipe line construction, maritime engineering, automotive construction and track construction.

Activities abroad

The foundation of the SLV-GSI Kunshan near Shanghai as the fifth foreign institute of the GSI has bundled up the former activities on the Chinese market. By the partnership with the power supply manufacturer EWM the GSI could use the existing experience and faci-lities at the location. Contrary to their principle known in Germany to offer a mix of power supplies of different manufacturers, the GSI cooperates with a special partner in this shop. This, however does not exclude the formation of similar partnerships at different locations. This is made possible by the great demand of highly qualified welders in China.

By the end of the year a workshop of welders was installed at the SLV-GSI Polska. Hence, the Polish subsidiary is also using the educational sector while the partnership with the Belgian company Vlassenroot has facilitate entering the market. In the workshop located on the works facilities not only welders of the compay Vlassenroot but also participants from other companies were trained.

A project in Egypt is dedicated to the topic of underwater welding which beside of the competences developed at the SLV Hannover also includes the regional experiences gai-ned by the GEWC. Both, the GEWC and the GSI therefore extend their activities which among others is reflected in the well-established education of welders in Kairo.

The business activities of the SVV Praha as well as those of the SGI-TR in Ankara have de-veloped positive. Certifications, construction supervision but also a successful education and training are the mainstays of the successful business activities.

On the eastern European market as well as in Russia further success could be made due to the active observation of the market. This has been underlined by founding a DVS work group „The Baltics“ and its first activities on the field of the qualification of engineers. A further example is the intensification of the cooperation with the Russian attestation company NAKS in Russia leading to a contract about the acknowledgement of welders certification tests. The accreditation of the center of attestation of the SLV M-V has also been re-confirmed.

Co-operating Institutes

The cooperating institutes of the SLV Halle GmbH, SLV Mannheim GmbH, SLV Mecklen-burg-Vorpommern GmbH, SLV Nord gGmbH as well as of the subsidiary TC Kleben GmbH belonging to the SLV Halle also had a similarly good business year as the GSI. The cause for this is also the excellent situation on the field of business of education and training.

Summer Festival of the GSI

The central highlight for all employees of the GSI was the summer festival celebrated at the SLV Halle. In spite of the instable weather the park like ground offered everything ne-cessary for a celebration in the shortest night of the year: a midsummer night.

The Fair Schweißen und Schneiden 2009 in Essen

On a four years basis the fair Schweißen und Schneiden which is the most important fair for the DVS and the GSI takes place in Essen. With the exhibition of all systems for the com-puter based education of welders currently available on the international market the GSI has initiated a new trend to its key business. Hence, it has become very popular with a lot of customers being interested. Beside of the own solution on equipment a special focus has been laid on the further development of the educational methods. Distance learning courses, too and computer based training were attractive offers.

The conclusion is that the computer based education of welders will be a central topic for qualified educational institutes in the future.

In 2009 the motto of the fair was of course: 10 years of GSI. Customers and partners of the GSI had been invited to join the fair party which was opened by a ceremony. 25 years of partnership of the GSI with the WTI Harbin in China were appreciated. It was pleasing that so many guests from Germany and abroad made use of the opportunity of exchanging their thoughts in a casual atmosphere.

The deep rootedness of the SLVs in the regional and national associations of the DVS serve to a joint cooperation being an important element of binding customers. Here, the transfer of technology takes place as daily cooperation. Thus, in 2009 the GSI organized common events at different locations offering the members of the DVS some interesting proposals. Some examples of this are the Duisburger Schweißtage with a new concept of cooperation with the regional associations of the Ruhr area and the national associations Nordrhein and Westfalen. The conference Schweißen im Behälter- und Anlagenbau in Mu-nich or the Nachmesse in Berlin are proof of common action.

Welding: Cool, clever, clean – and making fun!

The competition Jugend schweißt is a firm part of recruiting young people by the GSI. Therefore, the employees of the GSI are volunteers in qualifying contests on both, regio-nal and national level. As head of the committee Mr. Klein from the Bildungszentren Rhein-Ruhr was responsible for conducting the national competition on the fair Schweißen und Schneiden in a welding shop particularly created for this event. So it is even nicer to report that there were also winners among the apprentices of the GSI. The project PhanTechnikum of the DVS is something the GSI can identify with. Thus, it contributes both idealistically and financially while supporting the project leadership of this technical museum.

Blended Learning – Education of Welding Supervision Personnel in English

For more than 10 years the SLV Duisburg has been offering training courses for the edu-cation of international personnel in charge of welding (IWI, IWT, IWS), also in English. Until 2003 these courses had exclusively been carried out as classroom courses. Since 2004 the participants have had the possibility to perform the first part of the course as a distance learning course thus considerably reducing classroom time in Germany. 152 participants have concluded this distance learning course to date. Since 2009 the-re has been the possibility to perform also part 3 of the education as Blended Learning. Hence, Classroom Learning is reduced by 142 hours. Due to this educational concept the classroom phase is reduced from 3 ½ to 2 months while reducing the accommodation costs in Germany and the periods absent from the workplace; variable planning thus has become possible.The classroom phases of this newly designed took part in the months of May and October 2009 in Duisburg. 11 participants from Egypt, China, Greece, India, Ireland, Israel, Canada, Austria, Turkey and Cyprus after a short warming up phase successfully passed the inter-mediate examination after part 1 of the training.After that the use of goggles was required for observing practical exercises and to finally take the torch into the hand. During the last week of the first classroom phase the main field 1 of part 3 of the education was concluded by the written test. In October then, the-re was the second classroom phase where it was important to successfully conclude the main fields 2, 3 and 4. All of the participants passed the examinations and could proudly receive their certificates on the occasion of a ceremony held in a private brewery. The highlight of the event was the presence of a television team from the WDR who asked the participants on the quality of the beer. The distance learning courses and Blended Learning have been a constituent part of the scope of education by the GSI. Offering the course in English leads to a good position on the international markets.

Training Courses for GL-Ship Inspectors at the SLV Mecklenburg-Vorpommern

On behalf of the Germanischer Lloyd the SLV Mecklenburg-Vorpommern carried out nine training courses taking place a fortnight each with a total of 134 participants from Africa, North and South America, Asia and Europe between August 2008 and October 2009. The objective of the education was to familiarize particularly newly recruited ship inspectors with the basics of material testing and the welding processes. The subject is a well-known field of activity of the SLV. New, however, was the requirement to set up new and compre-hensive teaching material within a short period of time and to conduct the training course in English because of international participants.The training courses were opened by a Come-Together-event where participants and lec-turers could introduce each other.The training course itself started with an introductory test, in order to document the current state of knowledge and the progress of learning. Each of the following weeks of instruction taught both, theoretical knowledge and practical skills and ended with a test. Finally the SLV M-V handed over the certificates to the participants. Beside of the challenge concerning knowledge and language a further aspect was to be observed by the employees of the SLV: For the first time participants with different religions and from different cultural areas came together with the different habits of eating necessary to be considered.Summarized it can be stated that the training course designed as a basis for continual courses has got a good response with the participants. The exhausting education phases were relaxed by common events such as a tour on a fishing boat or bowling. Thus, opti-mized learning conditions could be created.

Ndt Training for Alstom in India

From 06.04. to 19.04. and from 27.04. to 12.05.2009 employees of the sector non-destruc-tive testing of the SLV Duisburg conducted an ndt-training for Alstom at its subsidiary in India in Durgapur, an industrial town (approx. 500,000 inhabitants) about 170 km north-west of Kolkata in the Indian Federal State of West Bengalen. The reason for the training was the aim of the company Alstom to extend both, qualification and certification of the ndt-personnel according to the European standard EN 473. In the first block the participants were educated in radiographic and penetration testing, in the second one in ultrasonic, magnetic particle and visual testing. With some excep-tions the participants had a basis of knowledge according to the American educational system ASNT-TC-1A and were able to make a level 2 examination according to EN 473 con-ducted by the TÜV Nord. All of the participants distinguished themselves by good intel-lectual grasp and a concentrated way of working. Due to the economic development of India an increased demand of education on the field of welding and testing technology seems very probable for the future; the preconditions for a further cooperation with the GSI are given.

New Ways of Education in Non-Destructive Testing

Since the year 2001 the GSI has been offering alternatives particularly developed and ack-nowledged for the scope of welding education in the form of distance learning cour-ses (CBT = Computer Based Training). These interactive learning programs have proven within the scope of training of personnel in charge of welding. In the year 2009 they were extended to the field of non-destructive testing and offered for the first time for the ndt-training course ultrasonic testing level 1 (UT 1) in accordance with EN 473. In the UT 1-distance learning course the multimedia possibilities at the PC are made use of. Beside of text and graphics, videos and interactive 3D animations are used that give a stepwise introduction to complex technical processes. Educational contents are taught near to practice, motivation remains at a high level. At the end of each chapter there is a control of the state of knowledge giving information on the learning progress of each of the participants.The UT1-distance learning course is offered as a so called Blended Learning-Concept. This concept offers a part of distance learning (CBT) and a phase of presence. The self study within the scope of the CBT covers a large part of the theoretical education of the basics while the focus of the following phase of presence is practical training. The blended lear-ning course permits to participate at the qualification testing with the possibility of a final certification in accordance with EN 473.

Ludwig Mies van der Rohe and the Digital Radioscopy

Ludwig Mies van der Rohe (1886-1969) is not only one of the most important architects of the 20th century but his furniture designs are considered milestones of design history. Until today his steel pipe and flat steel furniture – like the famous Barcelona armchair – is mostly produced in series. The armchair had been designed by Ludwig Mies van der Rohe for the exhibition hall of the Deutsches Reich at the world exhibition 1929 in Barcelona. Six of the armchairs were standing in the Barcelona exhibition hall; after the world exhibition they seemed to be lost. Arts experts can prove by analyses of manufacturing processes of the reef knots whether it is an armchair from the Barcelona exhibition hall or an imitation. The necessary radio-scopic examinations of the armchair found recently were performed at the SLV Duisburg using our digital radioscopic fully protected installation as used for the penetration test of welding specimens.With some of the welded joints cracks were determined through an optimized single beam geometry that could not be found by an optimized radiography. Cast parts, forged parts and similar were radiographed, in order to make inclusions visible.

With the help of a representation of gray scale with a high digitalization depth (12 bit = 212 grey scales = 4096 grey scales) the parts of different densities and thicknesses can be excellently tested and evaluated.12,000 radiographic films and the developing chemicals needed were saved in 2009 by the use of this installation. Further, due to the reduced radiation period both, the energy consumption and the load due to radiation was reduced thus making an important con-tribution to the environment. During the examination of the welded knot at the Barcelona armchair it could be proven that based on the manufacturing process the armchair was actually the one exhibited 1929 at the exhibition hall of the Deutsches Reich.

Magnetic Particle Testing on Galvanized Steel Engineering Structures

Galvanization is an economically and at the same time long term corrosion protection me-thod of steel structures. The hot galvanized steel structure has been able to gain market shares in plant construction engineering, multi-level parking lots and many other areas that are exerted to high corrosive loads. Parts having been galvanized with zinc melts and increased portions of tin and bismuth an increasing number of cracks have been found. The steel engineering and galvanization industries suffered a severe setback.Within the scope of a research project of the SLV Duisburg non-destructive testing of hot galvanized steel constructions were examined. Starting point for the efforts of a total of seven research projects was an increased formation of cracks at hot galvanized steel struc-tures observed from the mid of 2000. The cause of the complex mechanism of this forma-tion of cracks determined at the faculty of steel engineering and lightweight construction at the RWTH Aachen was liquid metal embrittlement. The individual influencing parame-ters – of the crack formation process were analyzed in detail by the research bodies.

Selected Projects

Magnetic particle testing turned out to be a practicable and economical testing method of non-destructive testing of hot galvanized steel structures that can be performed by qualified inspection personnel. By means of modification of the field initiation the su-sceptibility of proof for the test task could be incorporated as a constituent part of the new DAST-guideline 022 (hot galvanizing of supporting steel structures).

New Doha International Airport – Monitoring of Manufacturing and Construction Sites of the Cargo Handling System

Within the scope of rapid development of Qatar, a new airport is being built in the south of the capital Doha, the New Doha International Airport (NDIA) extending over an area of 22 km². About 2/3 of the area is located on an artificially created peninsula. With 2 run-ways the airport has been designed for about 320,000 flight movements with a capacity of about 50 million passengers and 1.35 million of tons of air freight (ULD system). The ULD system has a length of 395 m, a width of 27 m and a height of 20 m over 4 floors. HEM profiles as supports, IPE profiles as beams and hollow profiles as diagonals are the basis for the steel skeleton structure. A special challenge are the welded knots since face and head plate joints have been immediately connected to the knots resulting in connec-tions to the beams and diagonals difficult to join to the beams. The face and head plate joints are executed as pre-stressed bolted joints using HV bolts of the strength class 10.9. As a material the quality S275JR is used. Tonnage including secondary steel construction is about 2,000 t. On behalf of the company Lö-dige Fördertechnik GmbH the SLV Mannheim GmbH has taken over the steel enginee-ring and welding supervision of a steel company in Dubai (VAE) and later the monito-ring of construction site in Doha since September 2008. The completion of the steel structure has been planned for the first quarter of 2010.

The Waldschlösschen Bridge

The Federal capital of Sachsen currently is erecting a new bridge across the Elbe, in order to connect the northern parts of the city. The aim of this project severely discussed in the past is the reduction of the internal traffic in Dresden.In the total project Elbbrücke, planned with a total of 32 Mio. € the construction of the steel project is of central importance. The length of the superstructure, the mark has just been lined, is 636 metres. On both sides of the Elbe shore continuous bridges with a span between 30 and 80 metres have been arranged. The bridges are based on deflection re-sistant supporting pairs connected to the hollow caisson foundation. The river is over-bridged by two parallel, far visible and striking hollow caisson bows of a supporting width of approx. 140 m. The forces are diverted into the substructures via spherical bearings.The deck is hung to the bow through the stream. The traffic is conducted across the bridge in two double decks having total width between 24.40 m and 28.80 m. The supporting cross-section consists of two walkable hollow caissons, lateral supports for pedestrian are-as as well as a concrete plate. The connection between the materials steel and concrete is realized via in-situ concrete slabs welded onto. The steel composite beams have a width of 4.30 at the top and 3.30 at the bottom, they are stiffened by caissons and transverse beams and in longitudinal direction by trapezoidal hollow stiffeners. The distance of the axles of both of the hollow caisson is at about 9.60 m.

All types of plate thickness are leveled according to the changing loads. All of the joints have been welded. The maximum sheet thickness amounts to 70 mm in the stressed area and 175 mm in the pressurized area. The total weight of the steel superstructure was sta-ted to be 5,500 t. Based on the manufacturing possibilities in the works large and small sections up to part weights of 80 t could be pre-fabricated. For the parts below the deck construction covered with water in the case of possible high water of the Elbe a spray-applied galvanization instead of the zinc dust coating in ac-cordance with DIN EN 22063 in a nominal layer thickness of 100 μm was executed.

Thermally sprayed layers from zinc and aluminium and their alloys according to the buil-ding rule list require an assessment of load-bearing stability issued by an authorized body. Before, the SLV Duisburg had assisted the manufacturer and performed an initial type testing of the product for issuing a certificate for the system ÜHP in accordance with DIN EN 22063 (ISO 2063). The manufacture of the whole steel superstructure including corrosion protection was conducted by the company Victor Buyck Steel Construction in Eeklo, Belgium between July 2009 and probably September 2010. The building supervision by the SLV Duisburg, branch of the GSI mbH, comprises both, welding execution in case of workshop manufac-ture and assembly as well as corrosion protection of a surface of approx. 43,000 m².

Approval of the GSI as Manufacturer Certification Board in accordance with DIN EN 15085-2

Through the introduction of DIN EN 15085ff as a general rule of technology awarded in February 2008 by the German Railway Agency (EBA) for welding of rail vehicles and rail vehicle parts all of the manufacturer certification bodies approved in accordance with DIN 6700-2 received an approval fix-termed until 31.03.2009 for the certification of weld shops. The aim of the welding institutes of the GSI was it to receive the approval by the German Railway Agency as a manufacturer certification board „GSI“ as from 01.04.2009 after the expiry of a transitional period; the respective application was made in January 2010. Structurally, the GSI could present itself as a certification board with 9 regional or-ganizational units availing of a total of 29 experienced auditors. The general QM system of the GSI was the basis of the organizational structure of the manufacturer certification board. For safeguarding of a unique procedure for the certification and supervision of welding shops the certification and supervision of weld shops will be described in a de-tailed procedure specification.

Based on the proven competence, the German Railway Agency by letter dated 10.03.2009 awarded the GSI the approval as manufacturer certification board in accordance with DIN EN 15085-2 for a period of 5 years. Within the scope of supervision by the German Railway Agency it is regularly proven that this competence of the GSI and its auditors is maintained. This could last be successfully proven by an audit performed by the SLV Halle GmbH in December 2009.

By the end of the year 2009 the GSI had already registered 778 valid certificates in the online register rail vehicles (www.en15085.net) With a total of 1,230 entries the GSI assists about two thirds of all companies certified according to DIN EN 15085-2 which are active both, in Germany and abroad. The aim of the GSI is first to stabilize its market leadership in certification within the field of welding on rail vehicles and vehicle parts and then to further extend it. The basis for this is a skillful assistance by the inspectors and employees of the certification board of the GSI.

Bell Headed Nail Test

One of the largest German construction companies engaged the GSI mbH, branch SLV Duisburg to perform material scientific examinations on bell headed nails. On the basis of the results of the examination it was to estimate both based on theoretical and practical values since the bearing load of the nails due to corrosion of the cross section was not given any more. The bell headed nails were taken from a roof supporting system of a gable roof. According to the customer, it was hot galvanized bell headed nails the transverse beams of the roof had been fixed to. After approx. 5 years corrosion to the surface of the nail heads had been observed for the first time.There was the risk that the hot galvanized bell headed nails failed due to rusting, and the roof beams together with the roofing tiles could slide down. Hence, the examination was necessary, in order to determine by theoretical approaches whether and when the bearing load of the nails and therefore of the connection transverse beams/roof principal couples could be risked due to corrosion

Zinc coating is applied to steel parts for either corrosion protection purposes or for rea-sons of decoration. Corrosion resistance of a zinc coating is dependent on its thickness and its type of loading it is exerted to.

GSI SLV 2009 23

Selected Projects

The speed of atmospheric corrosion among others is dependent on the climatic condi-tions the part is exerted to. Thus, a higher rate of erosion is to be expected in an industrial climate than in a rural one. For reasons simplifying the estimation, a classification into so called categories of corrosivity is made. Beside of the location of the object for the analy-ses, the type of building influenced by the microclimate was considered. For determining the thickness of the zinc coating as well as of the actual diameter of the above mentioned bell headed nail, and also for determining possible traces of corrosion, destructive, metallographic examinations in the form of light and scanning electron mi-croscopic examinations were performed. Finally, the service life of the bell headed nail could be estimated on the basis of the results of the examination and a theoretical deduc-tion from the standards.

Uniform Regulation for the Execution of Trusses made of Steel and Aluminium

As early as on 21 December 1988 the guideline for the harmonization of the administrative rules of the member states for building products was published. On the basis of this gui-deline, the European Commission gave the Comité Européen de Normalisation (European Committee for Standardization) under the mandate M 120 the order to establish a uniform standard for the execution of steel and aluminium substructures.

On agreement with the German mirror committee Stahlbauten; Herstellung the emplo-yees of the SLV Duisburg looked after the work of standardization in the German standar-dization committee CEN / TC 135 WG 2 from the beginning to the end of the series. At the beginning, a rapid conclusion of the standards was planned but within the fol-lowing years it was shown that the demand of harmonization – also due to the incorpo-ration of the European Community – was much higher than planned. Moreover, the items of regulation of the Eurocodes 3 (steel construction) and 4 (steel composite construction) whose dates for termination were delayed more and more had to be observed. With the issue of December 2008, first parts 2 (execution of steel structures) and 3 (execu-tion of aluminium structures) could be published.

The missing part 1 of the series of standards DIN EN 1090 was published in October 2009. By this, all regulations that have to be observed in the future when executing these kinds of structures are available to the manufacturers of steel and aluminium. An instruction according to national technical approval, however, has still to be done. This is particularly valid for part 1 which rules the requirements of the proof of conformity for structures of steel, aluminium and composite materials from steel and concrete. The decisive publica-tion in the official document of the European Union, list C is still pendent.

As soon as this introduction has been realized, there will be a so-called phase of co-exis-tence. During this time the well-known standards DIN 18800-7 and DIN V 4113-3 are valid parallel of the standards DIN EN 1090-1, -2 and -3. Only after this phase of co-existence standards will DIN 18800-7 and DIN V 4113-3 be withdrawn.The single parts of the series of standards DIN EN 1090ff rule the execution of steel and aluminium structures as follows:

It is of particular emphasis that in the future the entire building product must be included for the evaluation. Hence, all decisive processes such as dimensions, welding, screwing and corrosion protection that within the scope of the fabrication production control must be performed, are to be evaluated.Due to the large scope of these standards and the huge number of the new rules connec-ted with it, the branches of the GSI mbH offer the respective seminars. These seminars deal with the principal requirements of the fabrication production control in accordance with DIN EN 1090-1 as well as of welding and screwing technology and corrosion protec-tion. The conversion of all requirements to monitoring and inspection plans is the final aim of the series of seminars.

MSG Welding of Nickel Base Coated Plates of a Flue Gas Desulphurization Plant

In flue gas desulphurization plants of fossil powered plants very high requirements are placed on corrosion resistance of the materials and welded joints due to the special envi-ronmental conditions (medium, temperature, pH value, dust etc.) In areas exposed to se-vere corrosion, such as the RVS channel Ni base roll bonded plates – NiCr23Mo16 (Alloy 59, material no. 2.4605) are used with S235. Joining of the plates by welding of the coated side to date has been performed both, manually and fully mechanized using the TIG welding process – under considerable time expenditure and a high heat input to the welded struc-

ture. Due to economic reasons, the use of MSG welding for assembly welding in the flue gas desulphurization plant of the power plant Boxberg, Block R, start of operation 2010, as well as for future projects was examined and qualified by the Babcock Noell in close co-operation with the SLV München. By the application of modern, electronic power sources and energy reduced material transfer at a high arc stability the cooperating partners have succeeded in successfully applying MSG welding both, partly and fully mechanized to all types of joints and welding positions performed at the FGD Boxberg. Compared to the MIG welding processes for closing of the cladding gaps at the roll bon-ded plates used to date, during welding with an energy reduced process for obtaining the required Fe contents of < 3 % in the cover pass facing the cladding, significantly less passes and beads are required. Due to the higher welding speeds welding can, in addition, be executed more efficiently and with a lower heat input to the construction.The use of the specialized MSG-welding was tested by the power plant operator Vattenfall Europe Generation AG & Co KG and afterwards released. Assembly welding at the FGD Box-berg Block R with an entire weld length of approx. 1,500 m have already been successfully concluded. The costs for the assembly of the roll bonded plates could be reduced by the application of the more efficient MSG welding, its attractiveness of whole metal constructions in the flue gas lines of flue gas cleaning plants could be increased again.

New Manual Welder at the SLV Fellbach

In 2009 an investment of a new laser system at the SLV Fellbach was made in the field research & development. Hence, the scope of education for laser welding could be exten-ded from the mere automated solutions to partly automated and manual welding solu-tions, respectively.Using this system building parts can be both precisely processed manually and via com-pound table (for parts up to a weight of 500 kg). For extra large parts there is the possi-bility to operate the laser as an open workplace. The average performance of the pulsed system amounts to 200 W. Further, the possibilities of education at the SLV Fellbach are to be extended and in the near future new training courses on the field of

· laser surfacing and repairs in tool and mould construction as well as · laser welding in microprocessing

are planned to be conducted. Within the scope of this investment also the facilities of the department research & deve-lopment will be redecorated and a new training room installed.

Thermal Processing of Free Plate Edges in Shipbuilding as a Precondition for Better Corrosion Protection

Within the program Schifffahrt und Meerestechnik für das 21. Jahrhundert a joint venture project having the title BeKaS – Entwicklung neuer Technologien zur Herstellung beschich-tungsgerechter Kanten im Schiffbau durch thermische Bearbeitungsverfahren (Develop-ment of new technologies in shipbuilding for the production of edges by thermal pro-cesses suitable for coating) was concluded in 2009. The project with a running time of 30 months was promoted by the Federal Ministry Economics and Technology and coordina-ted by the Center of Maritime Technologies e.V. (CMT). The aim of the BeKaS was the development of processes and tools for the substitution of the manual, post-treatment of edges in shipbuilding for the purpose of the preparation of coating to smooth, plate-shaped building parts through highly effective thermal proces-sing using laser or plasma beam.

Thermal „edge rounding“ using the solid body laser at sample plates to be coated later

The SLV M-V GmbH took over the process development of the tool solid body laser. Further partners used the CO2-laser and the plasma beam as a tool. Parallel examinations were performed with the project partner, Fraunhofer IFAM in Bremen on the service life of orga-nic coating systems at the edge, in order to prove the applicability of these new processes. Moreover, the possibilities and preconditions of a cost optimized integration in the ship-building manufacturing process were examined by further project partners.The project could be successfully concluded. The proof of equivalence of the thermally worked (rounded) edges with the manual, metal-cutting processes used to date was gi-ven from the point of view of corrosion protection. It was confirmed that the edge proces-sing works have a significant influence on the corrosion behavior and that by optimization of these processes also the corrosion behavior of the coating applied afterwards can be improved. Through the approval in principle awarded by the classification institute involved Det Norske Veritas (DNV) for the thermal processes for processing of free edges examined the development works could be concluded.

Fields and Limits of Application of Plasma Marking for Secure Welding

Due to the variety of the materials to be cut, the higher cutting speed with lower and medium material thicknesses, the short nonproductive times and the good opportunities of automatization, autogeneous cutting has more and more been replaced by plasma cutting as a common cutting process in the general metal processing industry.

Influence of different marking depths on the fatigue resistance of plasma marked specimens

For several years the user has been in the position by using new development on the equipment to apply a plasma torch both for cutting and for marking of building parts. However, no examinations have been made. Therefore, the objective of the research pro-ject was to analyze the fields and limits of plasma marking, in order to support the users when making technical and economic decisions on the use of the process. Within the project chosen topics of the very comprehensive scope of application were investigated. To this end, first the influences and interrelations of surface quality, surface treatment and surface coating were examined on visibility and durability of the marking. On the one hand reproducible parameters should assure that plasma marking after blas-ting and coating of the parts and during the planned service life is still visible, in order to fulfill the requirements of the national technical approval and on the other hand to assure a surface absolutely free from traces of processing after the completion of the building.

The focus of project processing was formed by material scientific examinations, in order to clarify the influence on the static and the fatigue strength of the parts. Microsections, structural evaluations and hardness measurements as well as tensile and notched bar im-pact tests were performed at specimens of chosen materials and different material thick-nesses of 3 to 10 mm. Examinations conducted by the SLV Halle GmbH resulted in the fact that by thermal influence of the parent metal the static strength will not be reduced. The geometric and metallurgical notches due to local concentrations of stress, however have an effect on the fatigue strength of the specimens.Compared to conventional marking with marking punch the plasma marked specimens show the same or higher fatigue strength values depending on the current intensity since the concentration of stress in the groove root is lower. The results of the examinations was compared with the IIW recommendations on fatigue strength of welded parts and assigned to the strength classes.

It was a success to build up a modular education of welders corresponding to the German quality standards and to advertise for the first measures. The DVS Media publishing house has supported this project providing instruction material in the Latvian language for the education of welders. The companies assisted by the GSI on the fields of steel construc-tion, mechanical engineering and rail vehicle construction will profit from this. Estonia with the TALLINNA LASNAMÄE MEHAANIKAKOOL in Tallinn has developed an im-portant location for the Eastern European network of the GSI. Here, training courses for personnel in charge of welding as well as VT 2 courses have been continuously performed for several years. In the previous business year we succeeded in making „welding joins“ a sustainable reality to 25 participants from Belarus, Russia, Lithuania, Latvia and Estonia. All of the participants successfully took part in the qualification program in accordance with the DVS IIW guideline and proved their expert knowledge against an international board of examiners.At the same time the GSI succeeded in working towards the foundation of a DVS com-mittee of welding experts enabling a common use of the GSI competence centers by the DVS on an international level, too. This project was accompanied in 2009 by a global se-minar of the EUROPEAN WELDING FEDERATION (EWF) with participants from 9 countries. Thus, the location at the border between Europe and Russia has promising perspectives, in order to realize the internationally demanded offers by the GSI also in this region and beyond with partners from industry and economy in the future.
