ABSTRACT:
A weld rod is prepared by placing a plurality of tungsten carbide/cobalt nuggets, preferably mixed with loose material, into a steel tube. The nuggets are previously sintered and have a generally ellipsoidal shape. A substrate is hard faced by progressively melting the weld rod onto the surface to be hard faced, and allowing the melted material to solidify on the surface.
