Tailored multi-material systems with thickness distribution by orbital forming

The utilization of multi-material systems is becoming increasingly relevant for future production technologies with regard to lightweight design and higher functional integration. Furthermore, improvements demand for new approaches that involve the integration of local material accumulation and a joining operation in a single step using an orbital forming process. The investigations are carried out on the basis of a demonstrator joining a steel ring and an aluminum blank. This involves the analysis of the mechanisms for joint formation, the identification of process limits, and the determination of a process window for the manufacturing of an adequate hybrid component.
