Underwater multifunctional stud welding device and welding method thereof

Abstract

The invention belongs to underwater welding cutting equipment, in particular relates to a underwater multifunctional stud welding device and a welding method thereof. The underwater multifunctional stud welding device mainly consists of a high-power welding power supply, a welding cutting set, an air supply system, a welding cable and a control system, wherein the air supply system comprises an air storage bottle, a pressure reducer and a corresponding air supply pipeline; and the welding cable comprises a welding ground, a cable fixing clamp, a welding gun welding cable and a welding gun control cable. The underwater multifunctional stud welding device has such characteristics as short welding time, good underwater welding quality, no need of operation by special underwater welders, reduction of fastening pieces and all-position welding, can realize such multiple functions as underwater stud welding, underwater manual arc welding and underwater electricity-oxygen cutting, and provides a whole set of solutions for such underwater emergency repair as damaged part repairing, repair plate stud fixation and reinforcement seal welding of damaged ships. The underwater multifunctional stud welding device can perform quick underwater repair without needing the ships to dock for drainage, so that the repair resource and cost are largely reduced, and the repair efficiency is improved.

Description

technical field [0001] The invention belongs to underwater welding and cutting equipment, in particular to an underwater multifunctional stud welding device and a welding method thereof. Background technique [0002] The so-called underwater emergency repair technology is a key technology for rapid treatment and emergency repair of underwater damaged parts of ships. The underwater emergency repair technology can enable the damaged ship to achieve rapid underwater repair on site, improve the maintenance efficiency and the ship's voyage rate, and achieve the purpose of quickly restoring the ship's vitality. In the past, when a ship was damaged or damaged, the underwater repair method was mainly the traditional plugging and repairing method, such as using wooden plugs, wooden boards, plugging boxes, plugging pads, quick-drying cement, and repair glue. Temporary repairs by bonding and other methods. The underwater leak plugging by means of these methods is only temporary, and ...

AI Technical Summary

Problems solved by technology

However, this method is difficult to operate and has poor controllability, which is greatly restricted in actual underwater operations.

[0004] In short, at present, there are relatively few on-site rapid repair technologies for damaged ships, especially underwater repair technologies, and the technology is backward, and the repair quality cannot meet the strength requirements. There is an urgent need for a new technology and new method to achieve rapid underwater repair.
