Abstract
An improved method and apparatus for the submerged arc surfacing of metallic work pieces with metal electrode strips melting in an electric arc while forming welding beads upon the work piece. The apparatus comprises a work piece which is to be surfaced, an electrode strip comprising the cladding material, means operative to move the strip and work piece relative to one another, a DC source, the opposite poles of which are connected to the electrode strip and the work piece, an electro-magnetic means having poles of opposite polarity operatively positioned at opposite sides of the electrode strip and adjacent the pool of molten flux and molten metal lying behind the electrode strip. The current to the electro-magnetic means is pulsed to thereby cause an agitation of the molten slag and weld deposit thereby resulting in a weld bead of extremely high quality, uniform thickness and also a defect-free tie-in between adjacent weld beads.
