Packer and Prof. J. Wardenier).

C-XVI / POLYMER JOINING AND ADHESIVE TECHNOLOGY Prof. David Grewell

It focuses on the standardization and certification programs, new education and training methods, digital and distance learning, training for intelligent manufacturing, education research, improving educator understanding of learning theory, and the image of welding as a profession.

C-XVII / BRAZING, SOLDERING AND DIFFUSION BONDING Dr Huaping Xiong

In 2022 we held a face-to-face intermediate meeting within C-XVII on 23rd June in Aachen, Germany, and we had 8 technical present ations. During the 75th Annual Assembly of IIW, 3 technical sessions were held by C-XVII on 19th and 20th July. In total 27 technical presentations were made, and the number of the attendeesA tendency of increasing contributions in the topics of machine learning and general data management. for the hybrid meetings was about 130. We had hot discussions especially on the topics of high entropy brazing alloy, Ga-or-Si-or-Sn based filler alloy, composite filler, ceramic-metal joining, induction brazing, and analysis of residual stresses and distortion of the dissimilar joints. In recent years we always encouraged people with an industrial background to join our commission and this time we collected 5 industrial background presentations. Furthermore, in the afternoon on 20th July we had a successful joint meeting bedtween C-VII and C-XVII. In 2022 we recommended 14 presentation papers to "Welding in the World". Furthermore, two experts (also principal reviewers) within C-XVII were recommended to enter the editorial board of WITW. A new Commission best practice document “IIW Recommendations and Best Practices for Welding Inspection – Tasks and Responsibilities" • A new Commission best practice document “Recommendations and Best Practices for Welding Coordination to ISO 14731 - Tasks and Responsibilities” • A new ISO standard on "Soldering - Quality requirements for structural soldering of metallic materials" jointly with Commission XVII • A new Commission document "Recommendations for competences for personnel involved in auditing to verify the compliance in accordance with quality system in the field of welding and allied processes" • Managing ISO 22688 "Brazing - Quality requirements for brazing of metallic materials" jointly with Commission XVII • Updating guidelines on the implementation of quality standards, for example, ISO 3834 "Quality requirements for fusion welding of metallic materials” C-XVIII / QUALITY MANAGEMENT IN WELDING AND ALLIED PROCESSES Mr Robert Shaw
