Abstract
Method and apparatus for simultaneously welding by the stud end welding technique a stud having two or more ends. The stud includes at least one elongated relatively thin metallic projection from each end of the stud to be welded. The method and apparatus maintains a current density in a given projection sufficient to disintegrate the projection with consequent arc initiation. The resultant arcs melt all stud ends and plate. The molten ends are lowered into the pools at a controlled rate at which time the current is extinguished and the material solidifies.
