Abstract
A dam, or barrier, structure is moved along the edge, or corner, of a workpiece to control the flow limits of molten material of arc welding. The dam structure provides a dimentionally stable groove at the edge of the workpiece surface into which is received granulated flux and positions the body of the flux along the edge, or corner, of the workpiece surface to function as a mold for the molten material, and, thereby, prevent the falling of the flowing material from the surface. The dam structure has the specific form of a continuous tread of segments which advances around parallel rollers to reform the retaining groove structure opposite the arc operation on the surface of the workpiece.
