Today’s industry implements modern materials and material combinations (multi-material design). Especially in the field of lightweight engineering, it is essential for joining techniques to meet requirements. Multi-material design is found in most sectors of industry and poses a major challenge for the joining technologies used. Many modern materials and their combinations can only be joined to a limited extent using conventional techniques or even not at all. For this reason, there is a need to continuously optimize or modify existing joining methods and to develop new technologies.
Extensive experience has been gained in conventional joining technologies, such as riveting, screwing, clinching and welding, as well as in automating these processes. Due to the enormous demands placed on joins, it is often no longer practical to apply conventional joining methods. The Department of Lightweight Construction Technologies addresses this problem by combining different technologies and optimizing processes, for example by superimposing vibrations. We also actively conduct research on state-of-the-art joining techniques, such as friction sir welding and bonding, to identify and further exploit their potentials.
