The arc welding robot interface, the digital arc welding inverter power supply, the diving wire feeder and the special welding torch for the robot are sequentially connected; the arc welding robot interface with one end connected with the robot is connected with the diving wire feeder and respectively connected with the compressed gas device and the protection gas device; the special welding torch for the robot is installed on the robot and connected with the miniature drainage cover, and one end of the special welding torch for the robot is connected with an arc load; the compressed gas device is connected with the miniature drainage cover, and the protection gas device is connected with the diving wire feeder. The welding system can automatically adapt to the characteristics of an underwater welding arc in the welding process, a stable welding power supply-underwater arc system can be established, and then high-quality underwater robot welding can be achieved.

Description

technical field [0001] The invention relates to welding technology and equipment technology, and more specifically, relates to a multifunctional welding system of an underwater welding robot. Background technique [0002] With the rapid development of the national economy and the urgent need of energy strategy, marine engineering is constantly advancing to the deep sea. As an important technology in the field of ocean engineering, underwater welding is receiving more and more attention. From the installation and construction of offshore oil and gas platforms to the laying and maintenance of submarine pipelines, from sea salvage and rescue work to emergency repairs of large ships, underwater welding can be seen everywhere. Research on underwater welding robots has promoted the development of the underwater welding industry. Compared with the previous manual underwater welding, underwater welding robots have higher welding efficiency, more reliable welding engineering quality...

AI Technical Summary

Problems solved by technology

In other words, the adjustment of the underwater welding process can only rely on the performance of the existing general welding system, that is, the process can only adapt to the power supply, and it is impossible to adapt the power supply to the underwater welding process.

Therefore, it is difficult for the existing power source-arc system to make the most effective control of the process according to the particularity of the underwater arc. It is very difficult to use land-based welding power sources for underwater welding to achieve stable arc combustion and good welding results. of
