In the case of a connection between two metal sheets which are arranged at a distance from one another by means of spot welding, one metal sheet being provided with an impression, which extends as far as the second metal sheet, in order to form a contact surface, it is proposed to provide at least one web of the impression in the region of each welding spot with a bead or recess in order that welding tools can nevertheless be introduced in the case of a narrow impression. |
