Thermal joining
The research group Thermal Joining of the Chair of Joining Technology and Assembly at the Technische Universität Dresden deals with process and joint analysis, resulting in application-oriented process developments. The focus lies on process evaluation and monitoring, process development and quality assessment of resistance welded, soldered and brazed joints.
