My name is Joel Andersson and I am professor of Material Science and Head of Division of Welding Technology at University West in Trollhättan Sweden. The Division of Welding Technology at University West comprises about 35 people (including senior researchers, PhD students and engineers) and focuses on three main areas in relation to welding technology; Metallurgy, Modelling of Process physics, and Process development and control. My field of research primarily covers welding and weldability of high temperature materials, in particular the precipitation hardening Ni- and Ni-Fe based superalloys. I’m currently supervising eight PhD students in corresponding research areas.
