Abstract

The invention provides a welding wire preheating gun. The welding wire preheating gun comprises a conductive seat, a first ceramic insulating sleeve and a wire output device. A joint for being connected with a heating power source and a first wire channel arranged in a penetrating manner in the axial direction are arranged on the conductive seat. A second wire channel is arranged on the first ceramic insulating sleeve in a penetrating manner in the axial direction. A third wire channel is arranged on the wire output device in a penetrating manner in the axial direction. The two ends of the first ceramic insulating sleeve are correspondingly connected with the conductive seat and the wire output device so that the two ends of the second wire channel can communicate with the first wire channel and the second wire channel. By the adoption of the welding wire preheating gun, welding wires are evenly heated, the utilization rate of energy is high, and use safety is achieved for the users.

Description

technical field [0001] The invention relates to a welding wire preheating gun. Background technique [0002] Hot wire TIG welding adds a wire heating system on the basis of ordinary TIG welding, that is, the welding wire is heated by an independent wire heating power supply and heating device, so that the welding wire is heated to 300 ~ 500 ℃ before being sent into the molten pool. Therefore, compared with cold wire TIG welding, the deposition rate of hot wire TIG welding is increased by six to ten times, thereby improving welding efficiency. [0003] The heating effect of the existing welding wire preheating system is poor, and the heating of the welding wire is uneven, which leads to unstable situations such as wire explosion and magnetic deflection during the welding process. [0004] In view of this, it is necessary to improve the existing welding wire preheating gun to solve the above problems. Contents of the invention [0005] The object of the present invention i...
