COMMISSION XI: PRESSURE VESSELS, BOILERS AND PIPELINES Sub-Commissions and Working Groups: C-XI-A: Correlation of Toughness Data Chair: Prof. Dr. Sonja Felber (Austria) C-XI-E: Transmission Pipelines

Commission XI and its sub-Commissions deal with any aspects of pressure vessels and pipe- lines that can be impacted by welding throu- ghout their life cycle. Commission XI brings together a unique mix of regulators, fabrica- tors, researchers, owners, material suppliers Chair: Eur Ing EWE Christoph Gerritsen (Belgium) C-XI-H: Performance of Welds for Hydrogen Service Chair: Prof. Dr. Bilal Dogan (United States)

and contractors. This group often collaborates with other IIW Technical Commissions to ap- ply their work toward the design, fabrication, life prediction and failure prevention of com- ponents, vessels and pipelines.

Chair: Dr. Teresa Melfi United States

COMMISSION XII: ARC WELDING PROCESSES AND PRODUCTION SYSTEMS

Vice-Chair: Prof. John Norrish (Australia) Sub-Commissions and Working Groups: C-XII-A: Sensors and Control Chair: Dr. Zengxi Pan C-XII-B: Arc Welding Processes Chair: Mr Stephan Egerland (Austria) Commission XII focuses on arc welding pro- cesses and production systems for promoting better practical applications in various indus- trial fields. Scientific and technical contribu- tions by Commission members emphasize sensors and process control, advanced arc welding process and underwater welding, production systems and applications, as well

C-XII-C: Production Systems and Applications Chair: Mr Satoru Asai (Japan) C-XII-D Underwater Engineering Chair: Prof. Ian Richardson (The Netherlands) C-XII-E: Quality and Safety in Welding Chair: Prof. Dr. Chuansong Wu (P.R. of China) as quality control and safety of arc processes. Together with Study Group-212, the Commis- sion works to establish more reliable welding and joining technologies with higher produc- tivities through a deep understanding of the physical phenomena governing the arc wel- ding processes.

Chair: Prof. Dr.-Eng. Yoshinori Hirata Japan
