The resulting product and a method of applying hard surfaces to gate valves and like generally planar metallic bodies which are subject to hard wear wherein a relatively thin generally planar facing plate is formed and applied to the face of the body to provide an assembly to be welded and a series of high power density welding beams of high energy electrons are directed at the face surface of the facing plate while moving the beams and assembly relatively in passes wherein the welds effected span the facing to secure the relatively thin plate to the body in a manner to avoid surface cracks, porosity and warpage to provide a hard wear-resistant facing for the body.
