Abstract
As preparation for the seam welding of different thickness sheet metal blanks (10 and 12), at least the thicker (10) of the two blanks is reduced in thickness, preferably by chip machining, in its edge region (11) which is intended for welding. Since the edge regions (11 and 13) which are to be welded then approximate to each other in their thicknesses (t1+t2), practically symmetrical conditions with regard to the joint plane exist for the welding operation, so that the welding can proceed with substantially the same controllable welding parameters as in the seam welding of sheet metal blanks of equal thickness. The process is suitable mainly for use in mash seam welding, but also in other seam welding processes, such as for example, in laser welding.
