[0002] Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. There are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction and ultrasonic. In addition to being used in factories, welding can also be performed in a variety of environments, such as the wild, underwater and in space. No matter where it is, welding may bring danger to the operator, so appropriate protective measures must be taken when welding.

[0003] Among them, when the valve is produced, the left and right side panels of the valve need to be welded with rib plates. The common welding method is: install the rib plates on the left and right side panels of the valve, and use a welding machine connected to a welding gun for manual spot welding. This welding method has low production efficiency and high labor costs. Therefore, the utility model proposes a valve automatic welding robot. Utility Model Content
