Collison welding is a promising material‐closed joining process that enables bonds with various advantages. It is already used as explosion welding to produce clad materials that cannot be joined otherwise. Other collision welding processes as electromagnetic pulse welding do not contain that amount of energy, but they can be used in mass production. In order to achieve a high process and product reliability, the process has to be designed accurately. But the process boundaries are not yet completely understood. In this paper, process windows for aluminium and copper joints, produced by a model test rig, are compared. Additionally, high speed observation and micro sections are used to enhance the knowledge about process boundaries and the influence of the jet.
