By a defined impact of two joining partners a material closed joint can be realized even between different materials that cannot be welded thermally. However, the industrial used processes are hardly observable, whereby the joining mechanisms are still not fully understood. While the observability in explosion welding is limited due to the explosives, the joining process in electromagnetic pulse welding is strongly transient as well.
The model test rig experiment has therefore been developed in order to be able to investigate the fundamental mechanisms of collision welding with high repeatability. Therefore an adjustable variation of individual process parameters with otherwise constant test conditions and good process observability are in the main focus.
