DETAILED DESCRIPTION
[0016] The following embodiments are used to illustrate the present invention but are not intended to limit the scope of the present invention.
[0017] Example
[0018] like Figure 1 and Figure 2 As shown, the welding gun device with a double tungsten electrode double wire mechanism of the utility model comprises a welding gun bracket 1, which can facilitate the external connection of the welding gun device. The welding gun bracket 1 is fixedly connected with an insulating holder 2 and a hot wire bracket, the welding gun is installed in the insulating holder 2, and the hot wire bracket is installed with a water-cooled hot wire cable and a wire feeding mechanism.
[0019] The interior of the insulating holder 2 is a cavity, in which a first welding gun 10 and a second welding gun 18 are arranged.
[0020] The first welding gun 10 is provided with a first tungsten electrode 5, and a first gas shielding channel is provided outside the first tungsten electrode 5. The gas inlet 13 of the first gas shielding channel is located at the top of the first welding gun 10, and the gas outlet of the first gas shielding channel is located around the lower part of the first tungsten electrode 5, so that the shielding gas can form a gas shielding effect on the first tungsten electrode 5 during welding. The first welding gun 10 is also provided with a first circulating water channel for cooling the cable in the welding gun, and the water inlet 11 and the water outlet 12 of the first circulating water channel are both located at the top of the first welding gun 10.

A water-cooled gas protection cover 4 is connected below the water-cooled gas protection plate 3.

The first welding wire 6 and the second welding wire 7 are staggered so that their heads are opposite and are located below the first tungsten electrode 5 and the second tungsten electrode 8. When the tungsten electrode is energized, an arc is formed, and the arc melts the two welding wires to weld the workpiece to be welded. The first hot wire bracket 16 and the second hot wire bracket 22 are respectively provided with a water-cooled hot wire cable outlet 24, and cooling water can pass through the water-cooled hot wire cable and then be discharged from the water-cooled hot wire cable outlet, which is used to dissipate heat from the water-cooled hot wire cable and the hot wire bracket.

When in use, the tungsten electrode in the welding gun is energized by an external power source, and the workpiece to be welded is energized at the same time, so that the two form a loop; then the welding wire is heated to reach the welding temperature; then the tungsten electrode and the welding wire are aligned with the welding position for welding to form a weld.
[0025] The utility model has a welding gun device with a double tungsten electrode and double wire mechanism. Two sets of wire feeding mechanisms are installed on a hot wire bracket. Welding wires are placed in the wire feeding mechanisms. The two welding wire heads are opposite to each other.
