Abstract
Method and apparatus for depositing metal on, and bonding it to, a metal part or parts, either to provide hard facing metal on the metal part or to produce a cast weld between the parts. In the method, the metal to be deposited is melted before depositing it by an induction coil supplied with high frequency electrical current. The metal part or parts are advanced toward a point where such metal is deposited, and in advance of such point, the surface of the metal part, or for welding, the surfaces of the metal parts to be joined, are heated to melting temperature by high frequency electrical current. The high frequency current is supplied to such surface or surfaces by the same induction coil, by a separate induction coil or by contacts engaging the metal part or parts.
