Conventional melting based welding processes are frequently insufficient to join modern functional materials. In the case of metals, this is for example true for many high strength aluminum alloys. The problem is even more difficult in the case of joining different metals such as aluminum and copper. Typically the melt forms intermetallic phases that drastically reduce the strength. Therefore at the IWS we develop new processes that avoid melt formation and the associated issues. Our primary focus is on friction stir welding and the electromagnetic pulse welding. We offer process development and prototyping services in these areas.
