Abstract

Disclosed is a local dry underwater laser welding system for simulating a deep water environment, comprising a welding system, a high-pressure gas control system, a fully enclosed water tank (1), anda movable welding table (11) arranged at the bottom of the fully enclosed water tank (1). The fully-enclosed water tank (1) comprises an upper end cover plate (25) of a tank body, a lower end cover plate (32) of the tank body, and a side plate. The high-pressure gas control system together with the fully enclosed water tank (1) forms a high-pressure environment and a stable local drying space, thereby realizing high-pressure underwater laser welding of a part (24) to be welded fixed on a belt of the movable welding table (11). The invention also discloses a local dry underwater laser welding method for simulating the deep water environment, which is convenient to operate and can safely and stably obtain a high quality weld through simulating a real deep water environment.

Description

technical field [0001] The invention belongs to the technical field of complete sets of underwater laser welding equipment, and more specifically relates to a partial dry underwater laser welding system and method for simulating a deep-water environment. Background technique [0002] At present, there is no suitable method for correcting the deformation of side beams in the field of rail vehicle maintenance. The traditional process uses thermal correction, that is, heating the deformed side beams and then correcting the side beams whose hardness has decreased. With the continuous deepening of human understanding of the ocean, the rich marine resources attract humans to deeper and wider ocean areas, and more and more marine infrastructures have been built. The establishment and maintenance of offshore infrastructure is inseparable from the progress and perfection of underwater welding technology. As a new type of automatic production process, underwater laser welding has th...
