[0002] The flange is a part that connects shafts to each other and is used to connect pipe ends. When welding the butt pipe and the flange, the joint needs to be welded. The existing technology generally requires the welding gun head to be rotated one circle for welding. The welding speed of this method is slow and the welding effect is poor, especially when overhead welding, the operation is very inconvenient. The existing welding machine does not have a rotating mechanism. The welder needs to manually rotate it on the ground to adjust the weld position and angle, which easily causes wear to the flange. It is not convenient to quickly rotate the butt pipe and the flange at the same time during welding, which reduces production efficiency and welding quality. Utility Model Content
