主权项 1. A process for laser welding at least one metal workpiece (1) by a laser beam (3), wherein the metal workpiece comprises a surface coating (2) and a lateral edge surface deposit (2a, 2b) on a lateral edge surface (1a) of the metal workpiece, wherein the surface coating (2) and surface deposit (2a, 2b) each contains mainly aluminum and silicon, and wherein the metal workpiece lateral edge (1a) has been previously formed by a cut by shearing, the process comprising the step of applying the laser beam (3) in combination with at least one electric arc (4) to melt the metal of the workpiece (1) and the lateral edge surface deposit (2a, 2b) to thereby weld the at least one metal workpiece (1) without formation of local aluminum concentrations in the weld of greater than 1.2%.
