Abstract

A method for welding components includes the following steps: providing a first component and a second component; bringing together the two components; welding the two components by use of a laser beam, wherein a plurality of welding impulses are generated through the repeated activation and deactivation of the laser beam, with each welding pulse being interrupted by welding-free rest intervals in which the laser beam is deactivated, wherein a local welding area is generated by each welding pulse, in which material of the two components is melted and fused in a locally limited manner, wherein individual welding areas of those generated by the welding pulses overlap.
