IIW Annual Report 2022

IIW WORKING UNITS

C-IX / BEHAVIOUR OF METALS SUBJECTED TO WELDING Dr Hee Jin Kim

To cope with the new developments in the design and welding processes, this commission is collaborating with other commissions and recently, faces a challenge to expand its scope into the material behaviours subjected to additive manufacturing.

C-X / STRUCTURAL PERFORMANCES OF WELDED JOINTS - FRACTURE AVOIDANCE Prof. Mitsuru Ohata

The revised version of “Terms of reference (X-1998-2022)” was approved and submitted to WG TWU. The draft “Operational Plan (X-1998-2022)” of C-X for the purpose of expanding targets and research items to be addressed in C-X was approved, whereas it would be advanced step by step with the suggestion of all members. The main activities are 1) Advancement of FFS standard, 2) Development of new assessment tools and 3) Establishment of WG. Taking a new initiative in additive manufacturing research by making a working group (or sub-commission) in C-X was also approved.

C-XI / PRESSURE VESSELS, BOILERS AND PIPELINES Prof. SuJun WU

During the Annual Assembly, Dr. Xing Sun (TWI, UK) was elected to be the Vice Chair of C-XI. Six papers were recommended for the journal and it was proposed to re-open the sub-commission XI-H: 'Performance of welds for hydrogen service' (to be approved). During the intermediate meeting, an international webinar with the theme of ‘Performance of Welds under Hydrogen Environments’ was successfully held online on 31st May, there were a total of 310 participants online fromall over the world.

C-XII / ARC WELDING PROCESSES AND PRODUCTION SYSTEMS Prof. Satoru Asai

In the Commission XII meeting at the 2022 IIWAnnual Assembly, 36 documents were presented from11 countries in two full-day sessions. Main topics included welding processes and production systems for high quality and efficiency, arc physics and monitoring& control for automation. As a new strategy, the intelligent manufacturing symposium concerning artificial intelligence, digital twin and virtual reality was organized. Also, the joint symposium for additive manufacturing was held with Commissions I and IV.

C-XIII / FATIGUE OF WELDED COMPONENTS AND STRUCTURES Prof. Kenneth MacDonald

The level of activity of C-XIII improved for the in-person Assembly and online intermediate meetings of the working group. Activity at the annual assembly was significantly increased over 2021 levels. 22 papers were recommended for the journal and work continues to complete final editorial review and publication of the document on Retrofitting Engineering for Fatigue Damaged Steel Structures. The guidance document for statistical analysis of fatigue data is progressing to publication expected in 2023. WG6 Chair position was filled by a long-term and very active member of the Commission with a fresh programme of work planned.

C-XIV / EDUCATION AND TRAINING Mr Carl Peters

The Annual Assembly in Tokyo provided the perfect venue for sharing best practics among member countries. We learned how nine countries improved teaching techniques, implemented digital and distance learning, and promoted welding standards and certification programs. There was a focus on involving young professionals, attracting the next generation of welders, and intelligent manufacturing. Three global leading universities presented on research programs, enrollment practices, student support, and industry relevance.
