ABSTRACT:
A welding device for building up metal for repair or construction of a metal bores, outside diameters and circular faces by laying down single or continuous metal weld beads in a pre-selected pattern; including a base member to receive a rotatable table with a drive is provided on the base to rotate the table at selected speeds. An elongated tubular spindle is provided to rotate with the table. Conduits for welding wire, welding current (power) and a shielding gas supply is provided to the spindle to supply gas, power and wire to the area adjacent the point of exit of the wire. The tip of the spindle serves as one electrode contactor in a welding process and the metal to be welded serves as the other. The spindle rotates with movement of the rotating table where the table includes a horizontal guide member to receive a slide member which carries the spindle and the slide member is longitudinally moveable in the guide to be selectively advanced and retracted by a variable horizontal feed device also located on the rotating table and where the rotatable table further includes a rotatable threaded connecting member to receive the spindle where the outside of the spindle is threaded so that upon rotation of the connecting member the spindle is raised and lowered relative to the rotating table.
