The auxiliary device comprises a first semicircular sleeve and a second semicircular sleeve for supporting a second pipe to be welded, a sleeve for driving the first pipe to be welded to move is arranged on the first semicircular sleeve, a connecting block is fixedly connected to the upper surface of the second semicircular sleeve, and a welding gun and a welding rod are inserted into the connecting block in a penetrating mode. A nozzle of the welding gun directly faces the joint of the second to-be-welded pipe and the first to-be-welded pipe, and a swing plate which is driven to swing in a reciprocating mode is arranged over the sleeve. Through cooperative use of the structures, the problems that in the actual use process, due to the fact that traditional steel pipe welding is mostly conducted manually and depends on the experience of workers, especially when steel pipes are pretreated and cleaned, cleaning is not in place, consequently, a zinc coating or a rusted surface cannot be comprehensively removed, a
