Abstract: A welding system (10) for welding a pipe (18) within a confined space includes a motor housing (11), a weld head assembly (12) remote from the motor housing and an insertion tube (13) extending between the motor housing and the weld head assembly. The motor housing is supported on a platform (17) for rotational and translational movement of the weld head assembly and houses a motor for positioning the weld head assembly relative to the pipe. The weld head assembly includes a clamp assembly (31) for attaching to the pipe and a weld tool assembly (30) mounted adjacent the clamp assembly for welding the pipe. An arc length gear (33) and a travel gear (34) adjust the distance between a torch assembly (38) and the pipe, and adjust the location of the torch assembly around the pipe when the weld head assembly is attached to the pipe.

Abstract: The present invention is directed to a pipe section (220)and a connector (400) that are adapted to be welded together, wherein each of the pipe and connector have inner and outer beveled surfaces and the joint is comprised of an angular alignment land (60). In one embodiment, an outer beveled surface on the pipe and an inner beveled surface on the connector cooperate to define the angular alignment land (60). In yet another illustrative embodiment, the inner beveled surface of the connector and the outer beveled surface of the pipe have a bevel angle of approximately 30 degrees, while the outer beveled surface of the connector and the inner beveled surface of the pipe have a beveled angle of approximately 45 degrees.
