IIW WORKING UNITS
C-I / ADDITIVE MANUFACTURING, SURFACING, AND THERMAL CUTTING Mr Ing. Doug Kautz
The Working Unit held two successful meetings, one at the Annual Assembly and the other a joint intermediate meeting held with Commissions IV, XII and Study Group 212. Members on the Commission are very active in international standards development and research and development in the areas covered by the Commission.
C-II / ARC WELDING AND FILLER METALS Dr Zhuyao Zhang
Commission II is focused mainly on welds produced by arc welding and on the filler metals which are used. Its activities centre on the metallurgy of weld metals, the influence of the chemical composition and minor elements on the mechanical, corrosion and damage weld behavior and on the reliability of welds in practical service. The Commission’s work is determined by various issues of filler metal optimisation and development in respect to metallurgy, new material grades, new arc welding processes and practical applications. Microstructural interpretation of weld metals, establishing of adequate test procedures for welds and standardisation activities in the area of filler metal specifications for arc welding are thereby the main tasks. Although there is a thematic overlap with other IIW Commissions in some general technical topics of interests, the differentiation from other commissions, especially Commission IX, is the technical approach to these topics. While Commission II focuses on the weld metal by a technology-driven approach, other Commissions are focusing on base metals which are subjected to welding from a more scientific point of view.
C-III / RESISTANCE WELDING, SOLID STATE WELDING AND ALLIED JOINING PROCESS Prof. Dr Ing. Jorge dos Santos
In the Commission III meeting at the 2021 IIW Annual Assembly, 21 documents where presented, originating from 10 different countries. Ten documents have been recommended for publication in Welding in the World . One resoltution was passed to establish a standardisation group (WG- B6) on Friction Stir Welding of Ferrous Materials. An Intermediate Meeting will be held in Paris 6 - 8 Februay 2022 and will have a ‘hybrid’ format (face-to-face and online). The Kick-off Meeting of the new standardisation group will be held at the same venue on 9 Februar 2022.
C-IV / POWER BEAM PROCESSES Dr Herbert Staufer
Commission IV operates like a ‘think tank’ for scientists, engineering and technical personnel who are involved in the research, development and application of power beam processing technologies including laser, laser-hybrid and electron beam welding processes.
C-V / NDT AND QUALITY ASSURANCE OF WELDED PRODUCTS Prof. Dr Marc Kreutzbruck
All five Sub-Commissions were active in the improvement and development of new nondestructive testing methods and their transfer into real test scenarios of welded components. In C-V-C we have almost finalised new TFM/FMC ISO Standards 23864 and 23865 detailing how to use new ultrasonic
