ABSTRACT:
A clinch weld fastener and method of using the same to effect attachment of a non-ferrous panel, such as an aluminum panel, to a ferrous panel, such as a steel panel. The clinch weld fastener is in the form of a clinch nut blank, preferably of the self-piercing type, with weld projections extending from one end thereof. To effect assembly of the two panels together, the clinch weld fastener is first clinched to the aluminum panel with the weld projections extending outward from one surface thereof and then after placing the aluminum panel with the weld projections in abutment against the steel panel, projection welding the clinch weld fastener to the steel panel thereby securing the aluminum panel to the steel panel.
