  • Publication number: 20150190878
    Abstract: An arc welding apparatus that imparts a rotational movement to the tip of the consumable electrode to cause molten metal to be thrown by centrifugal force against the sidewall of the slot between metal work pieces being welded. The welding apparatus being configurable to control speed, direction, and/or placement of the electrical arc in relation to the slot. The welding apparatus being configurable to pair with other similar devices and to be cooperatively operated in close proximity and\or on a single weld puddle to accomplish larger and/or complex welds in rapid, repeatable succession.

  • Patent number: 8127418
    Abstract: An apparatus for manufacturing structures having a continuous sidewall includes a stationary inner work station having at least one working level and a stationary outer work station having at least one working level. The outer work station surrounds the inner work station. A shaft is disposed between the inner work station and the outer work. A lift or hoist is provided for raising and lowering a work piece in the shaft as work progresses.
    Type: Grant

  • Patent number: 4401878
    Abstract: An arc welding apparatus that imparts a rotational movement to the tip of the consumable electrode to cause drops of molten metal to be thrown by centrifugal force against the sidewall of the slot between the two metal workpieces being welded.
    Type: Grant

  • Patent number: 4295031
    Abstract: A welding process, such as a GMA welding process, employs a consumable electrode with the consumable electrode being oscillated back and forth over the surface of an object to which welding material is to be applied or across the gap between two pieces of metal to be welded together. At the ends of the swings of the consumable electrode an impact force is applied to the consumable electrode to interrupt its movement, thereby causing molten metal at the end of the consumable electrode from which the arc is struck to be impelled therefrom.
