Abstract of the Disclosure The present invention provides a novel electrode construction and application for use in extrusion-fusion type battery intercell welders, which alters the current carrying characteristics of the electrodes and produces a homogeneous weld exhibiting a superior grain structure, higher strength, and superior durability. Each electrode comprises two portions, one of which is of steel and has a substantially higher electrical resistance than the other, which is of berylium copper, the copper electrode peripherally surrounding the steel electrode which is centrally located.
