Date Oct. 3, 1996A process and device for continuous butt-welding of metal sheets, in particular for car body building in the car industry, by beam welding. According to this device and process it is outlined that a precise abutting and welding of metal sheets is feasible without a precise alignment of metal sheets to be welded and laid on transport paths. This is accomplished by a special control of metal sheets to be welded together and by seam position sensors.
