FIBER LASER-BASE PIPELINE COUPLING SYSTEM AND METHOD OF INSTALLATION OF PIPE SEGMENTS

Abstract:

The disclosed laser-based method for pipeline installation includes of forming coronal formations on opposite wall ends of each pipe, continuously interengaging the corona formations of adjacent pipelines and welding a joint between the corona formations unto the desired pipeline length is reached. In particular, the disclosure relates to a pipe connection system including recessed wall ends of respective adjacent pipe segments which are enmeshed with each other to form a corona-like joint, and a laser system operative to weld the corona-like joint.
