Elaboration and qualification of a versatile process chain consisting of a pre-hole and joining process for industrial application (T07#)

• Subject Area: Primary Shaping and Reshaping Technology, Additive Manufacturing ; Joining and Separation Technology
• Term: since 2026
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 418701707

The project comprises the elaboration and qualification of a versatile process chain for the mechanical joining of pin structures in a previously shear-cut pre-hole. The aim is to transfer scientific conclusions from project C01 to an industry-oriented process chain for the production of a bicycle cassette. The use of a crossover aluminum alloy developed by AMAG in this process chain is expected to make a significant contribution. The aim of the investigation is to identify the process limits and develop a process window for the design of load-appropriate joints.
