    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.

    摘要： There is disclosed an arc welding process for stainless steel and a flux-cored electrode particularly useful therein. In one embodiment, means are provided for limiting the moisture content of the electrode as applied to the work piece. In another embodiment the electrode is formulated of components having relatively low moisture absorptivity.
