IIW 2016 Annual Report

SG 212 The latest activities of SG-212 focus on the pre- cise understanding of the welding arc, metal transfer and the weld pool through ‘visualisa- tions’ of the phenomena. Visualisation is based on 2D and 3D measurements and numerical simulations which provide us with an understan- ding of the mechanisms of the phenomena and thus help to ascertain scientific truths. SG-212 is contributing to the creation of technological innovation in welding process through research activities based on the physics of welding. This included the study of mechanisms of fusion welding with the aim of controlling and impro- ving weld quality and productivity, and the deve- lopment of useful simulation software for a new era manufacturing. To achieve these outcomes, the group is collaborating with C-XII, and also with C-IV and C-I. SC MICRO This Select Committee continues to focus on (1) microjoining and nanojoining processes as ap- plied to applications such as MEMS and NEMS, and medical devices and implants; (2) mate- rials (nanoparticles, nanolayers, etc.) used in microjoining and nanojoining; (3) methods and equipment used for quality assessment of mi- cro- and nano-scale joints; and (4) fundamental issues in microjoining and nanojoining, such as nano-effects. Because of increasing activity in SC-MICRO, this working unit has been approved to convert into Commission VII Microjoining and Nanojoining in 2017.

are necessary. Materials properties for lifetime prediction of thermoplastic materials is a new field, in which welding and joining technologies will become more involved in coming years. In thermoplastic welding technologies, the main topic was laser transmission welding. Research activities in Canada and Germany have started trying to get the same results in weld strength in both laboratories, as this is a precondition for comparable results in new technology develop- ments in this area. The next steps in this will be shown in our 2017 meeting in Shanghai. SC RES The Study Group meets during IIW Annual Assemblies and IIW Welding Research and Collaboration Colloquia. The successful 6 th Colloquium was held in 2016, at Hyderabad, India, as part of the Indian Institute of Welding Golden Jubilee celebrations. During the closing of the 2016 Colloquium, in line with the SG-RES vision on research strategy, cooperation and national welding capability, a recommenda- tion was raised from the attendees and sent to the IIW Technical Management Board. This re- commendation was that the IIW International Authorisation Board discuss, with the support of the SC-Air, the introduction of a harmonised special (non-compulsory) module on Aircraft Inspection into International Welding Engineer (IWE) and Inspection Personnel (IWIP) trai- ning courses. The 7 th IIW welding Research and Collaboration Colloquium will be held at TWI Ltd, UK, on 19-20 September 2017.
