Abstract
Methods of crack avoidance during resistance spot welding are provided. The compressive stress from the spot welding is distributed across an electrode assembly having an enlarged footprint. The electrode assembly includes a conductive core and a non-conductive cover. The delivery of current through the electrode assembly is localized to the conductive core.
