Abstract
An apparatus is designed for hard-facing internal combustion engines valves by the melting and fusion in high-frequency current field of heat-resistant rings of hard alloy upon the seating surface of the valves. The apparatus comprises an actuator means mounting gripping jaws and a support which is adapted to receive the ring and to feed it onto the valve stem at the moment the valve being gripped by the jaws. The actuator associates with a manipulator adapted to provide for turning movement thereof in two mutually perpendicular planes, thereby conveying the valve with the ring positioned on its seating surface from the receiving area fusion or welding zone, the valve stem being upwardly directed at the same time. The apparatus features high efficiency owing to combining the steps of putting the alloy ring on the valve and conveying the latter to the welding or fusion zone.
