Description

technical field [0001] The invention relates to welding technology and equipment technology, and more particularly to an intelligent arc welding robot submersible wire feeder. Background technique [0002] With the development of a series of large-scale projects such as marine energy, ocean transportation, and large ships, my country's demand for underwater welding technology is also increasingly urgent. There are three main ways to realize underwater welding automation: underwater orbital welding system, remote control welding system and robotic welding system. Underwater orbital welding needs to install the track underwater, which is limited by the diving depth of divers; remote control welding has a large precision error, and sometimes it is difficult to meet the requirements of engineering welding accuracy; based on the rapid development of special application robots in today's society, underwater welding robots are the future. Research direction of underwater welding a...
