    摘要: A system is disclosed for use in the production of valves that include a disk or head which is integral with an axiallyextending shank or stem. As disclosed herein, a form or blank of such a valve initially is provided (as by various metal-forming techniques) with an annular groove at the peripheral edge of the head. The valve form is then placed in a chuck to provide electrical contact with substantially the entire periphery of the valve head thereby affording a locus of short paths for heat flow and an arc-welding electrical current. In accordance herewith, the valve is then rotated in relation to an arc-welding apparatus to deposit an annulus of a specific form of hard metal in the groove of the valve. Finally, the valve is finished by smoothing the deposited annulus to provide a seating surface that will matingly engage an engine port to accomplish closure.
