C-XVII / BRAZING, SOLDERING AND DIFFUSION BONDING Dr Huaping Xiong
During the 74th Annual Assembly of IIW, 4 technical sessions were held by Commission XVII on 13, 15, 16 and 17 July, respectively. In total 32 technical presentations were made. The average number of attendees each day was 39. Among the 32 presentations ceramic joining, brazing of dissimilar materials, low temperature bonding, development of composite filler metals as well as electron beam brazing were the hot issues at the meeting. In recent years we have encouraged people with an industrial background to join our Commission, and this year we had 11 technical presentations coming from an industrial background or from cooperative projects with industrial enterprises. Furthermore, we had a successful joint meeting between C-VII and C- XVII on 16 July.
C-XVIII / QUALITY MANAGEMENT IN WELDING AND ALLIED PROCESSES Mr Robert Shaw
The Commission’s 2021 activities included the updating of guidelines on the implementation of quality standards, for example ISO 3834 ‘Quality requirements for fusion welding of metallic materials’, and the drafting of a new standard ISO 4061 ‘Soldering - Quality requirements for soldering of metallic materials’ jointly with C-XVII. We also worked on the drafting a new Commission document ‘Brazing coordination: Tasks and responsibilities’ jointly with C-XVII. Drafting recommendations for competences for auditors involved with the certification of welding companies was an area of work, as well as preparing comparative studies of criteria for welding company audits.
SG-212 / THE PHYSICS OF WELDING Prof. Manabu Tanaka
The SG-212 online meeting was held on Wednesday 14 July with a total of six papers and more than 50 attendees. The online meeting was well support by the IT Director and thus we had fruitful discussions among presenters and attendees. One document from the meeting was recommended for publication in Welding in the World. The members of SG-212 unanimously agreed a resolution on the disbandment of SG-212 and creation of C-XII Sub-Commission Physics of Welding under the new structure strategy of the IIW Working Units.
