Patent ID: 7741580

Claim:
A method for welding a pipe and a connector together at a weld joint comprising the steps of: forming only one inner beveled surface and only one outer beveled surface on an end of the pipe; forming only one outer beveled surface and only one inner beveled surface on an end of the connector, mating only the outer beveled surface of the pipe to only the inner beveled surface of the connector together such that the outer beveled surface of the pipe and the inner beveled surface of the connector are contacting along only a single tapered mating surface, to form an angular self-alignment land between interior and exterior portions of the weld joint between the pipe and the connector, and, performing only a single interior submerged arc welding pass to fill the interior portion of the weld joint with welding material, and, performing more than one exterior submerged arc welding pass to fill the exterior portion of the weld joint with welding material, thereby welding said pipe to said connector.
