Abstract:
Process for the production of a weld joint for at least three parts on a multiple stack, whereby parts are connected via a seam by means of a weldment, characterized in that at least a first and a second of these parts are welded together and are positioned along their seam at a distance from each other that is greater than the absolute magnitude of a shrinkage caused by the welding bead,in that in the area of the seam these two parts are provided with a recess which isdelimited by the two parts in the direction of shrinkage on surfaces facing each other, in that an abutting end of the third part is introduced interlockingly into the recess defined by the two parts and in that the first and the second part are connected by means of a weldment upon completion of this joining process.
