ABSTRACT:
A method of welding and a projection weld bond system is disclosed. A first workpiece is provided that is made of a material that conducts electricity, and a second workpeiece is provided that is made of a material that conducts electricity and has a plurality of projections formed therein. A materail is applied between each projections of plurality of projections, the material having electrical conductivity that is lower than the conductivity of the second workpiece. An area of the first workpiece is disposed at the plurality of projections of the second workpiece, and electricity is conducted through the first workpiece and through at least one of the plurality of projections of the second workpiece.
