IIW 2016 Annual Report

C XIV A very successful open workshop entitled Show- casing Successful National and Regional Activi- ties in Establishing a National Welding Capability (NWC) was held over two days during the 2016 Annual Assembly in Melbourne, attended by more than 50 people. The experiences and suc- cesses of many IIW Members are being conso- lidated into the NWC Project for the benefit of improving the global quality of life through the optimum use of welding. C-XIV is leading the part of the project related to the Education, Training, Qualification and Certification (ETQ&C) building block within such a NWC. The workshop included world-class speakers from Australia, Singapore, Poland, USA, Cana- da, South Africa, Portugal and New Zealand who showcased: the activities of WorldSkills Interna- tional (with which IIW has an MOU); successful welding Q&C management systems; skills deve- lopment and resources; projects promoting the image of welding; success stories in personnel and company certification; and latest develop- ments in digital training and simulation. A presentation was also given on the very successful 2016 Beijing ‘Arc Cup’ International Welding Competition, which is now supported by IIW. Besides being held in Beijing in June 2016, it will now also be held during the 2017 IIW Annual Assembly in Shanghai. C XVI The research in adhesive technology is main- ly influenced by the demand for lightweight construction with hybrid materials. There are many applications which require the joining of metals to fibre-reinforced plastics, which can be done by riveting methods and adhesive technolo- gies. For safe and reliable design in the automo- tive and aircraft industries, lifetime calculations

welds which will demonstrate distributions of residual stresses in weld metal and the heat af- fected zone the at surface, and inside of, welds for various types of grooves. Underlying factors in the guideline include a material hardening model, width-to-thickness ratio, phase transformation for high strength steel welds, thickness effect, groove geometry, and multi-run weld procedure. C XII In 2016 C-XII focused on Additive Manufacturing technology which potentially can increase design freedom of product and reduce part cost by re- ducing material wastage and time-to-market. Wire+Arc Additive Manufacturing (WAAM ), which originated from robotic/mechanised arc welding processes, uses an arc heat source and delivers a high deposition rate suitable for manufacturing large scale components. Arc welding processes have been progressed together with fruitful results of research and de- velopment spread by C-XII. In 2016, an IIW pu- blication entitled Implications of Recent GMAW Process Developments and Heat Input Research in Relation to International Fabrication Stan- dards reviewed the current status of advanced GMAW process developments and recent re- search on heat input determination. In particu- lar it considered developments which have been reported to C-XII over the last 30 years. After a brief review of the basic requirements for wel- ding procedure control the paper discussed the way in which welding fabrication standards may accommodate these developments.
