Abstract
The present invention relates to a system for spot welding with a laser beam () in which the laser beam () passes through a tube () and impinges on the components () to be welded together. The cross section of the laser beam () is formed by reflections inside the tube, and the distribution of the radiation intensity is homogenized across the cross section of the beam. At the same time, the tube () exerts a contact force (F) on the components () that are to be welded together. Using a plurality of laser beams (), to each of which a tube () is dedicated downstream, it is possible to create a simple and robust, component-specific system by means of which several or all weld spots can be simultaneously produced so as to conjoin the two components ().
