ABSTRACT:
A male spot welding electrode includes a weld end portion having a generally flat contact surface and a tapered mounting portion containing an inlet bore. The inlet bore communicates with an internal cavity, containing cooling fins, for coolant fluid flow. The diameter of the internal cavity is made larger than the diameter of the inlet bore in order to maximize the cooling surface for the dissipation of heat generated during repeated welding operations. The male spot welding electrode is produced from a single billet of copper material through a process of back-extrusion and swaging.
