The principle and the beneficial effect of the scheme are that: the second power source is arranged to establish a potential difference between the tungsten electrode and the welding wire, thereby creating a stable side arc between the branch tungsten wire and the welding wire and between the main tungsten wire and the welding wire. The method breaks the coupling relation between the deposition rate and the energy of the main electric arc, greatly improves the deposition rate, and improves the control flexibility of the welding seam. The coil can generate certain heat after being electrified, the welding wire in the welding wire welding gun is preheated, the heat efficiency of the electric arc for preheating the welding wire can be improved by matching with the side arc, and then the welding wire directly enters a welding seam molten pool after being preheated to a certain temperature.
