Abstract

The invention relates to a process and apparatus for the welding of strips 1, 2 without a filler by means of a laser beam 6. To keep the gap width of the joint edges formed by the strips 1, 2 at the joint as small as possible, disposed downstream of the welding focus in the direction L in which the strips 1, 2 run is a cooling device 10, 11, the cooling intensity is controlled to a constant small gap width in dependence on the gap width measured immediately upstream of the welding focus, referred to the direction L.
