IIW 2017 Annual Report

C-XV / Design, Analysis and Fabrication of Welded Structures / Mr Stefano Botta - Italy

residual stress and potential defects. Internatio- nal welding codes and standards used to regulate the final material properties were dissected and inspection techniques and failure analysis of ope- rating systems were presented. C-XII / Arc Welding Processes and Production Systems / Prof. Satoru Asai , Osaka University – Japan Our terms of reference cover the application of arc welding process to various fabrication fields. This year, extensive research and development of digi- tal manufacturing, based on physical models and/ or databases, was conducted. The number of pre- sentations on wire-arc additive manufacturing has increased exponentially year by year. Sharing our expert knowledge of sensors and process control, digital and additive manufacturing, and advanced welding processes and production systems pro- motes better practical applications in industry. C-XIII / Fatigue of Welded components and Struc- tures / Prof. Kenneth A. MacDonald , University of Stavanger | Statoil ASA - Norway

During 2017 a number of joint activities facilitated cooperation with other working units in order to share each one’s speci- fic knowledge. Our goals for the future are to seek more involvement in our meetings from industry,

and to promote the production of more technical documents based on our experts’ significant ex- perience in fabrication and erection of structures, both in the workshop and in the field. C-XVI / Polymer Joining and Adhesive Technology / Prof. David Grewell , Iowa State University - USA Our experts are involved in the development and dissemination of fundamental and applied knowledge on the joining of polymers, additivema- nufacturing and adhesives, and the joining of dis- similar materials to polymers. With 21 members attending meetings during the Annual Assembly, our group is one of the smaller IIW working units. There were, however, 13 excellent technical paper presentations in the fields of polymer welding and adhesive bonding and the group looks forward to continued growth in the future. C-XVII / Brazing, Soldering and Diffusion Bon- ding/ Dr Warren Miglietti President of Miglietti and Associates – USA

Our meetings focus on new scientific results, de- sign challenges and the application of new and innovative technologies to avoid fatigue failures in welded structures. Joint activities are held with other working units

concerned with closely allied subjects. A central feature is the fostering of young researchers, of- fering a friendly and knowledgeable forum for dis- semination and discussion of their work. We have recently developed several new science-based gui- delines that can be applied to challenging design and life extension cases, and the IIW Guidelines on Weld Quality in Relationship to Fatigue Strength is in the process of becoming an ISO document. C-XIV / Education and Training / Mr Carl J. Peters , Director of Global Educational, The Lincoln Elec- tric Company - USA We focus on five guiding themes in order to establi-

Our meeting in Shanghai was the most success- ful in the group’s history, with over 64 people in attendance, and 38 pre- sentations on the metal- lurgical and mechanical properties of materials, components and brazed/

soldered/diffusion bonded joints. On day-two we held a successful joint meeting with C-VII discus- sing areas of common interest in microjoining and nanojoining. Our experts are currently working with C-XVIII on Recommendations for Quality Re- quirements for Brazing. During the year, a very successful intermediate meeting was also held at the Technical University of Dresden. C-XVIII / Quality Management in Welding and Al- lied Processes / Mr Robert Shaw , President Steel Structures Technloogy Center, Inc. - USA Our interdisciplinary

group continues to work diligently on documen- tation and standards for quality in welding and is currently preparing a new ISO standard on Brazing – Quality requi- rements for brazing of

advanced trainers; and the image of welding/ career pathways. Presentations from Australia, South Africa, Portugal, Netherlands, USA, Cana- da, Spain, Germany, P.R. China, UK and Russia in Shanghai highlighted these countries’ best prac- tices relative to these themes. In addition to being practical and thought provoking, presentations helped prepare us for future challenges.
