Abstract

The invention provides a multifunctional underwater welding laser head. The problem that in a traditional laser welding method, due to poor waterproofness and pressure resistance of a laser head, thewelding effect is poor is solved. The multifunctional underwater welding laser head comprises a welding mechanism, a welding shell and a wire feeding mechanism. The welding mechanism comprises a laser, a spectroscope, a collimating mirror, a focusing mirror and a light transmitting element, and the output end of the laser sequentially penetrates through the spectroscope, the collimating mirror, the focusing mirror and the light transmitting element to reach a welding part. The welding shell comprises a laser head shell and a waterproof sealing cover. The wire feeding mechanism comprises a wirefeeder and a welding wire, the welding wire is arranged at the output end of the wire feeder, the wire feeding mechanism is arranged outside the waterproof sealing cover, and the welding wire penetrates through the waterproof sealing cover to reach the welding part. The multifunctional underwater welding laser head can be widely applied to the technical field of laser welding.

Description

technical field [0001] The invention relates to the technical field of laser welding, in particular to a multifunctional underwater welding laser head. Background technique [0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. The traditional laser welding method cannot meet the requirements of underwater welding. In the prior art, the underwater welding laser head with a moving gas shield is used to realize the underwater operation of welding. However, not only the structure is complex, but the waterproof and pressure resistance of the laser head are poor, and the welding effect is poor. [0003] Therefore, the traditional laser welding method has the problem of poor welding effect due to poor waterproof and pressure resistance of the laser head. Contents of the invention [0004] The purpose of this application is to provide a multifunctional underwater welding laser head, which aims to solve the p...
