Underwater pulse laser welding method and device for ocean platform

Abstract

The invention discloses underwater pulse laser welding method and device for an ocean platform. The underwater pulse laser welding device for an ocean platform comprises an ocean platform on which a laser is arranged; the side wall at the middle part of the ocean platform is transversely provided with a manipulator below which a laser welding head is arranged, and the inner part of the laser welding head forms a hollow cavity; and the laser is connected with the laser welding head through a transmission optical fiber. A pulse laser is fixedly mounted on the ocean platform, laser beams are output and conducted into the laser welding head by using a plurality of transmission optical fibers, the laser welding head is positioned and controlled to operate by the manipulator so as to adjust the pulse parameters of laser and reasonably select the output energy of the laser. The invention has the advantage of realizing automatic underwater unmanned welding, is beneficial to guaranteeing the position accuracy, the welding quality, the reliability of construction and the realization of automatic welding and improving the production efficiency.

Description

Technical field: [0001] The invention relates to the technical field of manufacturing ocean engineering equipment, in particular to an underwater pulse laser welding method and device for an ocean platform. Background technique: [0002] In recent years, with the increasing demand for energy, the development of offshore oil has been paid more and more attention. At present, there are nearly 10,000 offshore oil and gas platforms and their supporting offshore steel structures in the world. The operating depth of offshore oil has also gradually developed from the offshore continental shelf to the deep sea area. With the continuous development of offshore oil and gas development to the deep water area, the offshore platform adapted to the deep sea environment and used for offshore oil exploration and exploitation has become the main equipment for deep sea oil and gas development. Therefore, in the construction and maintenance of marine structures, urgent requirements are put f...
