    Abstract: In simultaneously arc welding studs with plural ends a problem exists maintaining the arc at each end of the stud. A method, welding gun (2) and specific stud (10) configuration are disclosed for maintaining the arc in stud welding. The stud (10) has one or more projections (19) extending from its ends (14, 15). The method and gun (20) initially maintains a current density in the projections (19) sufficient to disintegrate each projection (19) and start arc initiation. Thereafter, the current density in the ends (14, 15) of the stud (10) is maintained sufficient to sustain the arc with consequent melting of the stud ends (14, 15) and member (12) to which the stud (10) is welded while the stud (10) is lowered toward the member (12) at a controlled rate until the stud ends (14, 15) contact the member (12) at which time the current is extinguished and the molten material solidifies. The gun (20) has a footpiece (22) for alignment of the stud (10) and for maintaining in place arc shields (23) used in the method.

    Abstract: In simultaneously arc welding studs with plural ends a problem exists maintaining the arc at each end of the stud. A method, welding gun (20) and specific stud (10) configuration are disclosed for maintaining the arc in stud welding. The stud (10) has plural projections (19) extending from its ends (14, 15). The method and gun (20) maintains a current density sufficient to disintegrate only a portion of each projection (19), thus permitting the remaining projections (19) to contact the base metal (11) causing a short to extinguish the arc at one projection (19) while permitting subsequent arcing at the next projection that touches the base metal. The procedure, proceeds randomly from projection (19) to projection (19) until the ends of the stud (14, 15), reach the molten pool. The gun (20) has a footpiece (22) for alignment of the stud (10) and for maintaining an arc shield (23), used in the method, in place.

    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 only a portion of each projection with consequent arc initiation upon contact with the base metal such that the disintegration of a given projection will permit the remaining projections to contact the base metal causing a short to extinguish the one arc which has been initiated and consequent disintegration and arcing of the next tip to strike the workpiece which procedure proceeds randomly from tip to tip until the ends of the stud reach the molten metal pools. The studs and footpiece for the welding gun are of a configuration to insure proper alignment of the stud with respect to the workpiece while the footpiece of the gun includes means for securing to arc shields properly in place.
