The two side surfaces of the pipe are fixed, and the first push rod 402 can be driven by the first cylinder 401 to drive the welding gun 403 to be raised and lowered, so that the welding gun 403 fits the surface of the steel pipe for welding. At the same time, the fan 408 on the purification box 406 is started, and the fan 408 forms a negative pressure in the inner cavity of the smoke hood 404, so that the smoke generated during welding is sent into the purification box 406 through the smoke hood 404 and the smoke collecting pipe 405 for gas purification.
