ABSTRACT:
An end face of a work-piece having a circular opening is welded upon by apparatus which includes a stationary post mounted by a mounting assembly to the work-piece with its longitudinal axis coincident with the axis of the opening. A rotating assembly includes a sleeve rotatably mounted on the post and supporting a slide extending laterally from the sleeve. A weld head is supported by a carriage which reciprocates along the slide and has a weld electrode extending toward the end face of the work-piece. Rotation of the sleeve and movement of the carriage are coordinated so that a spiral weld pattern with overlapping turns is laid down on the end face. Cooling water and cover gas, as well as electrical power and control signals for GTAW-HW welding are delivered to the rotating assembly through rotating connections on the post.
