Abstract

An orbital weld head tool (10) has an orbiting and reciprocating carriage (22) for movement around a mandrel (12) fixed to a workpiece. Reciprocation is by a ball nut and screw drive means (70,74) driven by an arc voltage controlled motor (64). Rotation of carriage (22) with its ceramic shielded tungsten weld tip (16) and gas conduit (19) is by means of a separate motor (62) and drive belt (28). Power is supplied from a flexible hose connected through a conductive ball bearing assembly (30) and a conductive shoe (20) for weld tip (16) mounted on carriage (22).
