Patent ID: 7560662

Claim:
A welding apparatus comprising: a mounting assembly for adjustably attaching the welding apparatus to an adjacent structure, the mounting assembly having a first magnetic foot pad and a second magnetic foot pad, a tension support rod pivotally attached at one end of the first magnetic foot pad, an upper attachment pad pivotally attached at an opposite end of the tension support rod, and a bottom attachment pad pivotally attached to the second magnetic foot pad; a travel guide, the travel guide attached to the upper attachment pad at one end and the bottom attachment pad at the other end for selectively adjusting a position of the travel guide relative to the adjacent structure on which the first and second magnetic foot pads are attached; a head assembly attached to the travel guide, the head assembly having: i) a track ring assembly having an inner ring and an outer ring, ii.) at least two opposed weld torch heads attached to the inner track ring, iii.) at least one wire feed drive mechanism movable on the track ring, and iv.) a drive mechanism located on the outer ring of the track ring, the drive mechanism adapted to permit rotation of the inner track ring and the least two opposed weld torch heads; and wherein the head assembly is for alignment around a centerline axis of a component to be welded and a first weld torch head being for application of a first weld bead at an initial point; the inner track ring being rotatable by the drive mechanism to apply the first weld bead by the first weld torch head on a side of the component until termination of the first weld torch head; a second weld torch head being initiated adjacent to the initial point; and the track inner ring being rotatable in the reverse direction to apply a second weld bead by the second weld torch head on an opposite side of the component by the second weld torch head.
