The joining of shaft‐hub connections is gaining in importance in the area of power train applications. The quality demands in abrasion and power transmission are playing a major role. Dimensional as well as repeat accuracies are essential quality criteria, which have to be focused on. The understanding of the whole process chain in view of different distortion potentials introduced in each processing step provides the ability to control the distortion of the welded components. The laser beam sources of the new generation permit a high power welding process and high beam quality at the same time. These laser beams are capable of producing deep and narrow weld seams. This work deals with compensation strategies of deformations during laser beam welding in axial welded shaft‐hub joints made of steel. Furthermore, simultaneous welding with two laser beams and the influence of the process chain were investigated to characterise the influence of these strategies tactile differential measurements were done. The results were discussed regarding numerical calculations in the FEM application SYSWELD.
