ABSTRACT:
A weld-on nut is welded to a metal component to form a portion of a battery grounding terminal. The weld-on nut is tinned or galvanized with an anti-corrosion metal coating. The weld-on nut is welded to the associated sheet metal component by means of an electric resistance welding operation. In order to protect the contact surface from fusion of the tinning by welding spatters, an electrode contact surface on the nut is arranged axially offset relative to an electrode abutment surface or transversely to the latter. This weld-on nut can be of extremely light and small construction. The nut also requires provision of only a relatively small centering hole in the sheet metal in the region of the welding position, whereby the sheet metal component is only very slightly weakened.
