Abstract
Arc welding equipment having a welding tip mounted on a rotatable spindle in an offset relationship thereto, for making annular welds about the axis of the spindle. A cooling block is operatively connected to the spindle and is connected to a water supply for cooling the spindle and the welding tip. Inert shielding gas is supplied to the welding tip through a bore formed in a portion of the spindle and through a rigid water cooled tube which mounts the welding tip on the spindle. Consumable electrode welding wire is fed from a remote supply reel through the spindle bore and welding tip mounting tube with the inert gas to the welding tip. A commutator is mounted on the spindle and electrically connects the electrode wire in an arc power circuit. A workpiece centering tip is mounted on the end of the spindle and positions the welding tip with respect to the workpiece as the spindle rotates on its axis, with the welding tip forming an annular weld on the workpiece.
