Working group
The key concern of the working group is to analyse the increasing thermal and mechanical load as well as corrosion exposure of joined components and structures during fabrication, but in particular during service. Apart from the development of materials exhibiting corresponding load-bearing capacities, modern test procedures are required to an increasing degree in order to assure transferability of the results to real joined components as part of a closed test chain. It is therefore essential to understand not only the weldability as a component property, but also the later behaviour during service. This implies that most notably the design-specific boundary conditions need to be included in testing welded components. In consequence, the research activities of this working group were mainly focused on quantifying the relationships between material and structure. Various cold and hot cracking tests as well as the GAPSI 16 [pdf, 208 kB] large-scale testing facility are available for crack resistance assessment.
