| Abstract Scope |
A huge disadvantage of conventional friction stir welding (FSW) tools is that if the welding depth is insufficient, root defects can occur, which have a negative effect on the joint strength and especially on the fatigue behavior. Bobbin tools are used to counteract this weak point. These special tools have an additional second shoulder at the welding probe, which enables welding over the entire thickness of the workpiece. The possibility of producing tools from ceramic materials by means of additive manufacturing allows direct adaptation to the respective welding task. In this investigation, aluminum joints were produced by FSW using additive manufactured ceramic bobbin tools. Thereby, the running-in process in particular proved to be a critical stress for the ceramic tools. As a consequence, the process was investigated through simulation including shape optimization of the tool. This contributed to improve the joint formation in the simulation as well as the process. |
