Active participants in committee meetings during the conference of the International Institute of Welding 2014 in Seoul / Korea

At this year's IIW meeting in July 2014, representatives from the welding technical training and research institutions Munich, Hanover and Hall, representatives of GSI SLV Baltics, the SVV Praha and the GSI mbH were represented. The participation was carried out on several committees within the IIW in the area of ​​education and training, as well as in the technical and scientific work of the IIW.

GSI participants were Heidi Cramer and Mark Müller, GSI SLV Munich, Hans-Georg Gross, GSI SLV Baltic OU, Pavl Flegl, SVV Praha, Matthias Pöge, GSI SLV Hannover, Jan Neubert and Tobias Broda, SLV Halle GmbH, and Christian Ahrens , Roger van den Brekel and Klaus Middeldorf, GSI mbH.

Important individual results:

International Authorization Board – Group A (Training and Qualification) und Group B (Implementation and Authorization)

Discussed was the directive IAB 252 (DVS1170 welding supervisors). For this purpose, change requests are currently collected worldwide. Importantly are planned changes in the input condition "age" as that possibly be replaced by "experience of the participants." Further career opportunities from International Welding Practitioner for International Welding Technologist will be created.

The directive on the training of welding quality auditors (IWIP) is completely redesigned coming in 2015 on the market.

At the international exam questions database options to online exams are tested. .

The American Welding Society (AWS) arrangements have been made to offer distance learning courses for the International Welding Engineer and the International Welding Technologist in the United States.

The current state of IIW - audits were summarized, all IIW - including audits carried out in Germany audits were successfully completed.

Other operating points refer to the protection against forgery of IIW diplomas.

IIW Kommission Health and Safety
This IIW Commission day with a comprehensive program and a review of available IIW documents and standards in the areas of occupational safety in welding technology. There is an intensive exchange between European, American and Asian organizations on the implementation of the relevant regulations in the welding production, z. B. also compared the European regulations REACH and the Global Health international standards GHS. Of particular importance was the first time a current summary of all measures in the Health and Safety in the People's Republic of China.

IIW Study Group - Research
This group discussed research priorities in the member countries of the IIW. For this particular, a comparison of research strategies in the United States / (U.S. National Roadmap for Materials Joining and Forming Technologies) and Europe (Manufacture and Joining Platform). The aim is to further cooperation with coordination of research strategies. As technically interesting focus also the additive manufacturing processes are seen. Technical reports with applications from different countries show the increasing importance of this production and joining technology.

IIW Select Committee Quality Management
This Committee usually accompanies the international standardization in the field of ISO 3834 and its implementation. The example applications from Australia and New Zealand, the use of this standard for specific requirements ("seismic regions and seismic welding") is discussed. An overview of the quality criteria according to ISO 5817 in comparison with national production standards will be published shortly as an e-book. It continues an overview that includes an interesting comparison of quality management systems used worldwide in various industries. Also published by DVS Media - - Further, the revision of a document is done with the title "Improving the quality and effectiveness of welding by Utilizing the standard ISO 3834". This is an essential hand tool for the preparation and implementation of ISO 3834 certifications. The working group will increasingly deal with the future requirements for auditors, which are used in the field of certification of enterprises. Notice was given to the continuation of the GSI / AWS Events for comparison of the application of international standards in Europe and in the USA.

IIW Working Group Standardization
Participation in the meeting gives a good overview of current standardization projects in the IIW interaction with the ISO TC 44 discussions here include, for example, the implementation of ISO 9606-1 for the testing of welders during fusion welding of steel and the ISO 14731 on the tasks and responsibility of welding supervisors - here it is fundamentally about the informative annex to the assessment of competence, the welding supervisors. In addition to the discussion of individual standards was carried out a review of the various international standards, which have their starting point in the work of the IIW.

IIW Commission IV Power Beam Processes / IIW Commission XII Arc Welding Processes / IIW Study Group 212 Physics of Welding
The Commission IV meetings were in the form of lectures or as a joint workshop with the Commission XII (Arc Processes) and the SG 212 (Study Group Physics of Welding) instead. Meetings with lectures from Germany (12), China (4), Japan (3), and South Korea (3) were minted content.

Main focus was on new solutions and further developments radiating technical applications of the electron, the laser beam, and the hybrid welding. The joint workshop with the Commission XII and the SG 212 provides these applications then in direct comparison with the material behavior and the energy input when using more advanced or highly specialized arc welding technologies. The proportion of use of numerical welding simulations takes to predict the material behavior and to visualize the dynamic keyhole formation with beam welding clearly. It was noticeable also that generative laser-based manufacturing processes and coating technologies are playing an increasingly important role in building up welding with the laser beam with a total of 6 posts.

The GSI SLV was represented in this topic with a lecture to metallurgy and strength behavior produced by laser cladding with wire pulsed solid-state lasers coatings. With respect to the additive manufacturing process has further been reported from the USA via the formation of an AWS-working group D20 for the development of standards and guidelines regarding design, material selection, quality and personnel. A professional highlight was a report on first experiences during laser welding with a 100 kW fiber laser in atmosphere and in vacuum.

Commission XIV Education and Training – Welding Training Systems
In this workshop, the status and the development of welding trainer systems, the systems of Lincoln, Soldamatic, RealWeld system, 123 Certification, GSI SLV and Toshiba were presented and partially demonstrated by live demonstrations. The presented system operates by Toshiba camera-based and records the attitude and the movement of the welder from different perspectives in TIG and MIG welding of pipe and Blechprüfstücken for subsequent analysis of skills by the welding teacher. The focus, however, continue to form virtual reality systems, which work with simulated welding processes in a virtual environment. The GSI SLV welding trainer, which in contrast, operates with a reduced but real arc for TIG and MIG welding, was also presented. Here, in addition to the basic principle and operation of the prior art system also changes in the layout and the interactive training plan were described.

Commission III Resistance Welding, Solid State Welding and Allied Joining Processes – SC-Auto Select Committee Automotive and Road Transport
This commission reflects the importance that increasingly the Friction Stir Welding plays. Many contributions were determined from lightweight. The joining of light alloys and high strength steels stand in the focus of discussions. The topic of lightweight determined the conducted jointly with the SC car event. Made concerning, for example, with the highly localized metallurgical conditioning of high and ultra high strength steel.
