Abstract

The invention belongs to the field of underwater laser processing and particularly relates to an underwater carried gas and water coaxial jet auxiliary laser processing system. The underwater carriedgas and water coaxial jet auxiliary laser processing system comprises a laser device, a sweater cooling system, a seawater desalination system, a pure water cooling system and a laser-gas and water coaxial jet coupling head. The sea water cooling system is used for cooling the laser device and a sealing cabin. The seawater desalination system is used for desalinating seawater into pure water through a reverse osmosis sweater desalination device. The desalinated pure water is used for cooling laser crystals which cannot make contact with seawater, and the pure water is used as jet water of thecoupling head. By means of the above seawater desalination system, the seawater cooling system and the pure water cooling system, the laser device and the coupling head are assisted in forming laser-gas and water coaxial jet, and the surface of a workpiece is machined. By means of the device, seawater resources are effectively utilized for achieving the cooling function, the service life of key parts is prolonged, and the machining quality of an underwater laser processing system is improved.

Description

technical field [0001] The invention belongs to the field of underwater laser processing, and more specifically relates to an underwater air-water coaxial jet assisted laser processing system. Background technique [0002] Laser processing has been widely used in onshore workpiece cutting, drilling, welding, cleaning, and surface treatment. When working underwater, due to the influence of the water environment, the structure, control and even the interaction of the laser material of the processing object are very different from those of land-based laser processing equipment and processing quality. The watertightness of the equipment, the precision of motion control, the structure and weight of the equipment itself, the conduction and focus control of the laser, and other factors all bring difficulties to underwater laser processing. With the popularization of underwater operating environments such as ocean development and nuclear power applications, the prospect of underwat...
