IIW 2017 Annual Report

C-I / Additive Manufacturing, Surfacing and Ther- mal Cutting / Ing. Doug Kautz , Group Leader at Los Alamos National Laboratory - USA Work has focused on a range of thermal cutting and surfacing activities, as well as the relatively new area of additive manufacturing (AM). Coor- dinating through the TMB, we are working with several other Commissions to ensure adequate information exchange and research to enhance AM’s application in different industrial sectors. The development of standards applied to AM will facilitate its adoption by industries that require high levels of quality and data gathering. Discus- sions in the area of thermal cutting development have seen exchange of information about the three major processes used as well as the stan- dards to be applied. C-II / Arc Welding and Filler Metals / Dr Gerhard Posch , Vice President of Knowledge & Data Ma- nagement and Vice President of the welding ACA- DEMY at Voestalpine Böhler – Austria

quality and reliable solutions are now available for a number of applications of multi-material joining in present day structures. A joint meeting with SC-AUTO on day-two attracted representa- tives of industry and academia while a seminar with C- XVI on ‘Hybrid Metal-Polymer Joints’ and presentations from Sub-commissions III-A and III-B completed the programme, attended by around 70 people each day. C-IV / Power Beam Processes / Dr Herbert Staufer , Team Leader High Power Welding at Fronius - Austria

Basic research into power beam processes, especially electron beam and laser beam pro- cesses, is our primary focus. The combination of laser beams with different arc modes was covered in both the an-

nual and intermediate meetings. One research highlight was the use of power beam processes for additive manufacturing with powder or wire of different metals. These processes are in a conti- nuous state of rapid development and advance- ment as new technologies and innovations offer a nearly unlimited array of welding, joining and processing opportunities. C-V / Non-destructive Testing and Quality Assu- rance of Welded Products / Dr Eric Sjerve , Chief Technology Officer at IRISNDT – Canada

Our primary focus has been on high-strength, creep-resistant and nic- kel-based filler metal weld microstructures using standard charac- terisation methods and also thermodynamic cal- culations and atom probe

tomography. Furthermore, investigations in res- pect to the role of hydrogen in weld metal cracking were continued and the revision of ISO 3690 Wel- ding and allied processes -- Determination of hydrogen content in arc weld metal was started. Round robins on analysis of fluxes and tramp ele- ments were finished and, based on the results, po- sition statements for ISO Technical Reports were drafted. C-III / Resistance Welding, Solid State Welding and Allied Joining Processes / Dr-Ing. Jorge Dos Santos , Head of Department ‘Solid State Joining Processes’ at Institute of Materials Research - Germany

Our group made good progress with its work in 2017 that included: revision of ISO 24497 Non-destructive testing - Metal magnetic me- mory; continued work on full matrix capture/ total focussing method

(FMC/TFM) standardisation of advanced imaging techniques for ultrasonic testing; digital refe- rence radiographs; joint work with other Com- missions on additive manufacturing; publication of the simulation assisted probability of detec- tion book; and publication of a structural health monitoring book.

A popular seminar on the ‘Application of Re- sistance and Friction Processes for Dissimilar Joints’ was held on the first day of the Annual Assembly. Presentations demonstrated that high
