Welding tool for outgoing line

The invention discloses a welding tool for an outgoing line. The welding tool comprises a cooling device and a clamping device, wherein the cooling device is provided with a tubular structure, and two ends of the cooling device are opening ends used for being connected with water pipes. During operation, the two ends of the cooling device are connected with the water pipes, the outgoing line is press-fitted on the upper side surface of the cooling device through the clamping device, then the welding is performed, and the purpose of cooling is achieved through a water flow flowing inside the cooling device. According to the welding tool for the outgoing line, the outgoing line is clamped through the clamping device and then welded, so that the positioning operation of the outgoing line is rapid and accurate, the improvement on the working efficiency is facilitated, and the welding quality of the outgoing line is guaranteed. In addition, the water flow passes through the cooling device both in a welding process
