Beschreibung
Zusammenfassung:	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. L'invention porte sur un procédé par laser permettant une installation de pipeline qui consiste à former des formations coronales sur des extrémités de parois opposées de chaque tuyau, à mettre en prise continue les formations de couronne de pipelines adjacents et à souder un raccord entre les formations de couronne jusqu'à atteindre la longueur de pipeline souhaitée. En particulier, l'invention concerne un système de raccordement de tuyau comprenant des extrémités de paroi renfoncées de segments respectifs de tuyaux adjacents qui sont engrenés l'un avec l'autre pour former un raccord de type couronne, et un système laser conçu pour souder le raccord de type couronne.
