ABSTRACT:
A welding electrode made of dispersion strengthened metal wherein the electrode tip is pressure formed or forged to reorientate and/or destroy the coaxial fiber structure and form a non-axial grain structure in the electrode tip portion. The electrode is produced in a method for pressure flowing a blank by applying axial pressure to pressure flow the blank transverse to the axially applied pressure whereby the overall strength of workpieces such as welding electrode rods is substantially increased.
