Research group Thermal Joining

© Kretzschmar

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.

• Resistance welding
• Soldering and brazing
• Destructive and Non-destructive testing

Overview of research activities

Welding, soldering and brazing by means of resistance heating

• Process development from the idea to the prototype
• Joining-process developments for Multi-Material-Design
• Process parameter window identification and strategic improvements of process safety and handling
• Destructive testing for reliable quantification of specimens (tensile, compression, shear, peel, head tensile, torsion)
• Development of new non-destructive testing methods
• Ultrasonic and magnetic field simulation for weld detection
• Process simulation performed by own FEM-models in ANSYS
• Fundamental research on processes in the joining zone and in particular on processes at the interfaces

Joining, cutting, coating and straightening by means of induction heating

• Inductive inert gas furnace soldering and brazing

Welding, soldering and brazing by means of vacuum or inert gas furnace

• Effects and behavior of the aluminum surface
• Solderability considerations
