In order to counteract climate change and the scarcity of resources, functional lightweight construction involving multi-material construction is gaining in importance. This is used, for example, in electromobility and aerospace. A major challenge here is the safe joining of dissimilar materials, e.g. aluminium and steel.

One possible solution is collision welding. In collision welding, the joining partners are joined by plastic deformation by colliding with each other through a relative movement. The aim of this work is to investigate the influence of varying process parameters, such as collision angle and speed, on hardness distribution in the joining zone. The work packages of the scientific work are

The creation of a test plan for parameter variation and the realization of the tests on the Institute's own test rig for aluminum and steel material combinations

Determining the hardness distributions that form.

A personal meeting can be arranged to discuss further details.
