Welding metallurgy research is aimed at obtaining a fundamental understanding of the influence of welding heat input on the properties of high-strength low-alloyed and stainless steels. The focus is on the microstructural changes that occur in the various sub-zones of the heat-affected zone, and the influence of these changes on mechanical and corrosion properties of the steel. The research is based on the use of physical simulation and the analysis of real welds. There is close cooperation with the other groups in the research unit and other universities and research establishments, e.g. with respect to the testing of real welded components for verification of models and simulations.
