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.

Method for welding components

A tool for laser beam processing is provided. The tool includes an upper tool and a lower tool, which are able to be advanced toward one another by way of a press, such that at least one component is able to be fixed in a predefined position between the upper tool and the lower tool. At least one laser beam exit surface, which is part of an inner surface of the upper tool or lower tool, and at least one laser beam guide, into which laser radiation is able to be coupled and is able to be directed through the laser beam exit surface onto a processing location on the component are provided. A control device, which enables and/or disables the coupling of laser radiation into the at least one laser beam guide depending on the advancing movement between upper tool and lower tool is provided. Furthermore, a laser beam processing apparatus and a method for laser beam processing are also provided.
