Abstract
A system for spot welding two metal sheets together includes a plurality of conductive particles placed in an interface between the two metal sheets, a first electrode, and a second electrode. The first electrode and the second electrode are arranged to clamp the two metal sheets together such that the conductive particles become embedded into the metal sheets at the interface between the metal sheets. A conductive path is formed from the first electrode to the second electrode through the metal sheets and the plurality of metallic particles.
