Title: METHOD FOR WELDING COMPONENTS
Abstract:
The invention relates to a method for welding components (1, 2) comprising the following steps: providing a first component (1) and a second component (2); bringing together the two components (1, 2); welding the two components (1, 2) by means of a laser beam (5), wherein a plurality of welding impulses are generated through the repeated activation and deactivation of the leaser beam (5), with each welding impulse being interrupted by welding-free rest intervals in which the laser beam (5) is deactivated, wherein a local welding area (11-22) is generated by each welding impulse, in which material of the two components (1, 2) is melted and fused in a locally limited manner, wherein individual welding areas (11-22) of those generated by the welding impulses overlap.
