ABSTRACT:
A welding head employs a carriage assembly for guiding the welding head along a track or guide. A torch assembly, mounted on the carriage assembly, is configurable for multiple welding processes. The torch assembly includes a torch block and a GTA filler wire guide mounted together on a mounting plate, whereby the GTA filler wire guide is placed in general proximity of a welding torch mounted on the torch block. The torch block accommodates the mounting of either of a GMA torch and a GTA torch. Additionally, the torch block accommodates placement of a GMA adapter sleeve within the torch block to feed a filler wire through the GMA torch. A system control unit provides manual, semi-automated, or automated control of welding system resources including a welding power supply, a supply of one or more shielding gasses, and a fluid coolant supply.
