Abstract
A method provides for joining an outer sheet and an inner sheet, in particular of an attachment part of a motor vehicle body. On the visible sides of an attachment part, a welding or brazing seam is produced between a fold of an outer sheet and an inner sheet. The outer sheet is held in a bed, and the inner sheet is pressed against the fold on an inner side thus forming a joining groove. To ensure that during beam welding or beam grazing the inner sheet is held in position on the fold, it is prevented from moving away without clamping by stops on an outer side. These stops are disposed in a row along the welding or brazing seam and in dependence upon the progress of the joining procedure can be moved individually out of a path of a welding or brazing head.
