ABSTRACT:
A system and method for welding projection weld nuts to a work piece. The system and method of the present invention generally makes use of a fixtured work piece having one or more projection weld nuts associated therewith. A resistance welding robot is used to weld the projection weld nuts to the work piece. The welding robot typically has weld electrodes therewith, through which electric welding current is passed to the projection weld nut(s) and the work piece. A first and second contacting electrode is used to transfer electric current from the welding robot electrodes to the projection weld nut(s) and work piece.
