ABSTRACT:
An improved resistance welding electrode cap adapted to being internally cooled with a flow of coolant has a main body portion with a nose root at one end and an electrical and coolant connection projecting from the other, the area of the root being substantially smaller than that of the direct projection of the main body portion, a pronounced nose projecting from the root. The whole nose is of dispersion-strengthened copper, as is at least the main body portion. Such cap provides astonishingly improved performance for resistance welding, even of galvanized steel, and particularly of double-sided, galvanized cold-rolled steel sheet.
