Abstract

See full text

A method of adhesive weld bonding a light metal workpiece and a steel workpiece is disclosed that includes applying a plurality of discrete adhesive ribbons to a faying surface of the light metal workpiece, the faying surface of the steel workpiece, or both faying surfaces, and then assembling the workpieces together to establish one or more adhesive zones between the faying surfaces of the light metal and steel workpieces and a plurality of adhesive free zones amongst the adhesive zone(s). The method further includes forming a resistance spot weld that bonds the the light metal workpiece and the steel workpiece together at a spot weld location within one of the adhesive free zones. The formed spot weld includes a weld joint contained within the light metal workpiece that bonds to the faying interface of the steel workpiece.
