WIPO Patent Application WO/2018/002907
Kind Code:
A3
Abstract:
A system for welding two pipes includes a first pipe clamp, a second pipe clamp, a weld torch, an inspection detector, a motor, one or more processors, and a grinder. The weld torch is configured to create a weld joint between the pipes at an interface region between the pipes. The inspection detector is configured to emit an inspection beam of radiation. The motor is operatively associated with the inspection detector to direct the inspection beam of radiation along the weld joint between the pipes. The one or more processors are operatively associated with the inspection detector to determine a profile of the weld joint between the pipes. The grinder is configured to grind at least a portion of the weld joint between the pipes based on the profile of the weld joint between the pipes.
