Abstract
A field system for welding two pipes includes a first pipe engagement structure, a second pipe engagement structure, one or more weld torches, a motor and one or more processors. The one or more weld torches are configured to be positioned within the pipes to create an internal weld at an interface region between the pipes. The motor is operatively associated with the one or more weld torches to rotate the one or more weld torch along the interface region between the pipes. The one or more processors control the motor and the one or more weld torches. The one or more processors operate the motor and the one or more weld torches to generate a complete circumferential weld along the interface region by rotating the one or more weld torches along the interface region in a single rotational direction until the complete circumferential weld is completed.
