Abstract
A method for the end-side welding of at least two metal sheets disposed on one another in sections, includes selecting welding parameters such that, in the metal sheets to be connected, at least one of which is composed of a high-strength steel, a temperature with which the high-strength steel of the at least one metal sheet is tempered is generated at least in direct vicinity of an end-side weld seam. In addition, through a suitable selection of the welding parameters, a weld pool volume forming the weld seam is generated at an end side of the metal sheets. The weld pool volume has a width greater than the width of the end side of the metal sheets. Therefore, an undercut can be generated between the outer sides of the metal sheets and the weld seam. A form-locking connection can thereby be generated between the metal sheets and the weld seam.
