Novel flame welding gun

The utility model relates to a novel flame welding gun which mainly comprises a switch, an air inlet pipe, a branch connector, a left welding pipe, a left welding head, a right welding head and a right welding pipe. The integrated welding gun made of copper materials is in the shape of a clamp forceps, the switch is arranged at the corresponding position of the air inlet pipe, the branch connector is positioned at the end of the air inlet pipe, gas entering from the air inlet pipe is distributed into the left welding pipe and the right welding pipe, one end of the left welding pipe is connected with the branch connector, the other end of the left welding pipe is connected with the left welding head, one end of the right welding pipe is connected with the branch connector, the other end of the left welding pipe is connected with the right welding head, and the left welding pipe, the left welding head, the right welding head and the right welding pipe are symmetrical. By the aid of the flame welding gun, a traditional single-surface welding mode is changed into a double-surface welding mode, the novel flame welding gun is simple in structure and low in cost, mainly, the uniformities of welding spots is improved, empty welding and leakage welding possibilities are greatly reduced, and product qualification rate is greatly increased.
