Device for spot welding with laser beam

The invention relates to an apparatus for spot welding with a laser beam (6), wherein the laser beam (6) by a tube (3) to the components to be welded (7.1, 7.2) is guided. the beam cross section of the laser beam (6) is formed by reflection in the interior of the tube and homogenized radiation intensity distribution over the beam cross-section. At the same time via the pipe (3), a pressing force (F) to the components to be welded (7.1, 7.2) is applied. With a plurality of laser beams (6), which in each case a tube (3) is disposed downstream of a simple and robust components specific device can be produced with the more or all welds for connecting the two components (7.1, 7.2) are produced simultaneously.
