The combination of different metallic materials, such as aluminium and steel or aluminium and titanium, by firmly bonding via laser beam welding enables the production of customised hybrid lightweight designs with enhanced properties. Both weld geometry and local material behaviour, which are responsible for the final load characteristics of the compound, are influenced by the process parameters during welding. A novel approach of coupling process, microstructure and mechanical simulation, considering the development of weld geometry and local material conditions is intended to deliver a fast and reliable method for evaluating the quasi‐static strength of laser beam welded hybrid compounds. Besides the objective to promote a reduction of expensive welding experiments, the developed method can enhance the performance of hybrid structures as well as their lightweight potential for automotive and aircraft applications. The experimental determination of the local mechanical properties as the basis for the regarded simulation approach is an essential part of a running research project.
