IIW Annual Report 2021

IIW WORKING UNITS

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

Commission XI is concerned with the welding and welds in pressure vessels, boilers and pipelines. During the 74th IIW Annual Assembly in 2021, a total of eight papers from five different countries were submitted and presented at the two-day C-XI sessions, and five of the papers were then recommended for publication in the journal Welding in the World. The Panel Discussion session in the second day was very fruitful and really helpful for C-XI’s future activities and development. C-XI has also co-organised the International Symposium on Structural Integrity (ISSI 2021) held in Hangzhou, P.R. China in October 2021. An intermediate meeting is being planned.

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

The annual meeting of Commission XII took place from July 15 to 17 2021 online with 16 presentations and attendees numbering 112, that was 90 and 91 respectively. C-XII covers the application of arc welding processes to various fabrication fields and production systems with high quality and efficiency. Also, digital manufacturing and additive manufacturing are a focus of discussions. The sessions were full of wonderful presentations and hot discussions. In this meeting, the new Sub-Commission F “Physics of Welding” was created in Commission XII.

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

The level of activity of C-XIII improved in the face of the ensuing pandemic intermediate and Spring and annual meetings of the working groups were held. Activity at the online Annual Assembly was significantly increased over 2020 levels. Sixteen papers were recommended for publication in Welding in the World and work continues to complete the final editorial review and publication of the document on Retrofitting Engineering for Fatigue Damaged Steel Structures. ISO/TS 20273:2017 (Guidelines on weld quality in relationship to fatigue strength) has been adopted by a sufficient number of countries for it to pass ISO's systematic review.

C-XIV / EDUCATION AND TRAINING Mr Carl Peters

Commission XIV continued making progress in sharing best practices related to qualification programmes, the effective use of advanced training systems, gender diversity in welding, the involvement of Young Professionals in IIW and advancements in welding training.

C-XV / DESIGN, ANALYSIS, AND FABRICATION OF WELDED STRUCTURES Dr Eng. Stefano Botta

In the C-XV meeting held during the online Annual Assembly, seven technical documents were presented, and all of them were proposed for peer rewiew and publication in Welding in the World . Furthermore after the report of the judging panel, the Chinese builders of the Hong Kong Zhuhai Macao Bridge was proposed to the TMB for the awarding of the UGO GUERRERA PRIZE 2022. As for the administrative matters, Prof. Ben Young and Prof. Tak-Ming Chan both from the Hong Kong Polytechnic University have been elected as new Co-Chairs of Sub-Commission XV-E Tubular Structures in place of the retiring Co-Chairs (Prof. J. Packer and Prof. J. Wardenier). Finally, the current Chair of the Commission XV Stefano Botta was confirmed as Chair for the next three years.
