Avoiding distortion during the laser beam welding of shaft-hub joints

摘要

Beam welding processes are suitable for the thermal joining of shaft-hub joints since deep and narrow seams can be produced with them. Deep, narrow seams entail minimal thermal loads on the components to be joined and thus permit a low-distortion welding process. Nevertheless, fabrication-induced geometrical deviations which are often associated with high subsequent machining costs on the finished part (e.g. in the region of the power train) may nevertheless arise especially because further distortion potentials may be introduced within the process chain of the fabrication technology.
