IIW 2014 Annual Report

COMMISSION II: ARC WELDING AND FILLER METALS Sub-Commissions and Working Groups: C-II-A: Metallurgy of Weld Metal Chair: Dr. Thomas Kannengiesser (Germany) C-II-C: Testing and Measurement of Weld Metals Chair: Dr. Zhuyao Zhang (United Kingdom) C-II-E: Standardisation and Classification of Weld Filler Metals Chair: Mr David Fink (United States)

Commission II identifies, develops and transfers scientific and technical information, possibly leading to International Standards or best practices, with respect to Arc Welding and Filler Metals. Its principal areas of focus include the metallurgy of weld metal (e.g. Hydrogen in weld metal, chemical reactions, constitution of weld metal and weld metal cracking), as well as the testing and measurement of welds (e.g. ferrite in high-alloyed weldmetal, corrosion testing and testing of weld metal for hot cracking and micro-fissuring). It is also involved in standardization of welding consumables, including the coordination of the evaluation of ISO standards which are under Systematic Review, assuming responsibility for appropriate testing standards and conducting round- robin tests as may be required in support of the general work programme. These activities have greatly contributed to the understanding, acceptance, classification and adequate use of welding consumables.

Chair: Dr. Gerhard Posch Austria

COMMISSION III: RESISTANCE WELDING, SOLID STATE WELDING AND ALLIED JOINING PROCESSES Sub-Commissions and Working Groups: C-III-A: Resistance Welding and Allied Processes Chair: Dr. Jerry Gould (United States)

C-III-A-WGA1: Testing of Welds Chair: Mr André Galtier (France) C-III-A-WGA2: Monitoring and Control Chair: Dr.-Ing. Miro Uran (Slovenia) C-III-WGS: Standardisation Chair: Dr. Kin-ichi Matsuyama (United States) C-III-B: Friction-based Processes Chair: Prof. Dr.-Ing. Jorge dos Santos (Germany) C-III-B-WGB2: Mechanical Properties Database

Chair: Dr. -Ing. Jorge dos Santos Germany

Chair: Dr. Antonio da Silva (Spain) C-III-B-WGB3: Modelling for FSW Chair: Dr. Laurent d’Alvise (Belgium) C-III-B-WGB4: Standardisation on Friction-based Spot Welding Processes Co-Chairs: Prof. Dr.-Ing. Jorge dos Santos (Germany) and Mr Marc Petersen (United States)

Commission III provides a unique forum for open discussion, where highly-competent international experts exchange scientific and technical information and transfer knowledge about resistance welding, solid state welding and allied joining processes. In recent years, topics have included joining of dissimilar thin sheet materials,

joining in automotive industries, computer simulation of joining processes and friction stir welding, including both modelling and weldability. The Working Unit also assists in the formulation and preparation of new International Standards, with a view to encouraging and supporting a safe, healthy and environment-friendly world.
