The dust suction device 3 is installed at the end of the welding gun 1, and the dust suction device 3 is attached to the workpiece to cover the smoke and splash as soon as they are generated, so that the welding device has a self-cleaning function. The wire feeding system 2 is installed at the bottom of the welding gun 1, and the wire feeding system 2 extends into the inner side of the dust suction device 3 to feed the welding wire into the bottom of the welding gun 1. The protective air pipe 5 and the exhaust gas exhaust pipe 6 are all extended into the dust suction device 3, the protective air pipe 5 is fed into the protective gas, and the exhaust gas exhaust pipe 6 extracts the exhaust gas. Each pipe plugging device 4 has an open and closeable sealing end and the pipe plugging device 4 is connected to the protective air pipe 5. The protective air pipe 5 is fed into the protective gas, so that the protective gas is passed into the pipe workpiece, so that the inside of the pipe workpiece also has protective gas, which can more fully protect the workpiece weld position and reduce spatter. The tracking device 7 is installed at the bottom of the welding gun 1 and the tracking device 7 is located in the dust suction device 3, so that when welding, the welding gun 1 can be guaranteed to move along the weld track when the dust suction device 3 is blocked.

[0038] Specifically, the wire feeding system 2 includes a wire feeder, a wire feeding tube 21 and a wire feeding copper tube 22. The wire feeder feeds the welding wire into the wire feeding tube 21. The wire feeder is a prior art and will not be described in detail here. The wire feeding tube 21 is installed at the bottom of the welding gun 1 to provide a guide for the feeding of the welding wire. The wire feeding copper tube 22 is installed at the end of the wire feeding tube 21. The wire feeding copper tube 22 is closest to the molten pool and is made of copper to prevent burning.

[0039] Specifically, the dust suction device 3 comprises a dust suction clamping device 31, a ring-shaped dust suction cloth 32, and a plurality of dust suction control plates 33 which are installed on the ring-shaped dust suction cloth 32 in a radial manner, the dust suction control plates 33 are installed on the ring-shaped dust suction cloth 32 by means of adhesion, and the plurality of dust suction control plates 33 can support the ring-shaped dust suction cloth 32, preventing the ring-shaped dust suction cloth 32 from collapsing into the molten pool position and causing damage, the dust suction clamping device 31 comprises two pieces of dust suction clamping sheets 311 which are installed by means of bolts, and the two pieces of dust suction clamping sheets 311 have clamping ability, and the middle part of the ring-shaped dust suction cloth 32 is clamped between the two pieces of dust suction clamping sheets 311, and it is particularly noteworthy that the dust suction control plate 33 is provided with an integrated clamping portion 3211 and an elastic portion 3212, the dust suction clamping device 31 clamps the clamping portion 3211, an included angle is provided between the clamping portion 3211 and the elastic portion 3212, the elastic portion 3212 has elasticity, and the elastic portion 3212 is a spring steel sheet, so that each elastic portion 3212 can drive the ring-shaped dust suction cloth 32 to adapt to the position of the pipe and fit the pipe, which helps to suppress dust and splashing, the ring-shaped dust suction cloth 32 is a glass fiber cloth coated with silicone rubber, the two pieces of dust suction clamping sheets 311 of the dust suction clamping device 31 are installed at the end of the welding gun 1 by means of bolts in the form of a screw pair, and the ring-shaped dust suction cloth 32 is provided with two air pipe through holes 321, and each air pipe through hole 321 passes through the protection gas pipe 5 and the waste gas exhaust pipe 6 respectively.

[0040] Specifically, the pipe plugging device 4 comprises a hollow deep pipe 41, a central control sheet 42, a pipe plugging sealing device 43, and an opening clamping device 44, the pipe plugging sealing device 43 forms a blocking end, the central control sheet 42 is installed at the end of the hollow deep pipe 41, the pipe plugging sealing device 43 is installed on the periphery of the central control sheet 42 in an openable and closable manner, the opening clamping device 44 is installed on the central control sheet 42, and the opening clamping device 44 is in transmission connection with the pipe plugging sealing device 43, after the pipe plugging sealing device 43 is opened and blocks the pipe workpiece, the hollow deep pipe 41 communicates with the protection gas pipe 5.

[0041] Specifically, the plug tube sealing device 43 includes a plug tube annular sealing cloth 431 and a plurality of plug tube sealing plates 432. The plug tube annular sealing cloth 431 is installed around the central control plate 42 by bolts. A pressure plate is provided between the bolts and the plug tube annular sealing cloth 431. The pressure plate can disperse the pressure of the bolts on the plug tube annular sealing cloth 431. The plug tube sealing plates 432 are radially installed on the plug tube annular sealing cloth 431. The plug tube sealing plates 432 are installed on the plug tube annular sealing cloth 431 by gluing or sewing holes in the plug tube sealing plates 432. The clamping device 44 is transmission-connected to the corresponding plug tube sealing plate 432, and the clamping device 44 is opened. The device 44 pushes the plug tube sealing plate 432 to rotate, so that the plug tube sealing plate 432 presses against the inner wall of the pipe workpiece. At the same time, the plug tube sealing plate 432 drives the plug tube annular sealing cloth 431 to open, thereby sealing the pipe workpiece. It is worth noting that if the workpiece to be welded has several outlets, several plug tube sealing devices 43 must be set up. Since the plug tube annular sealing cloth 431 is soft, the plug tube sealing plate 432 and the plug tube annular sealing cloth 431 are both inclined toward the direction of the weld to be processed. In this way, when the shielding gas is injected toward the weld, the plug tube annular sealing cloth 431 will be pushed by the pressure of the shielding gas to fit the inner wall of the pipe workpiece.

[0042] Specifically, the opening and clamping device 44 includes a plurality of opening and clamping sliders 441, an opening and clamping connecting rod 442, an opening and clamping control rod 443 and an opening and clamping control rope 445. The opening and clamping control rod 443 slides along the hollow deep tube 41, and one end of the opening and clamping control rope 445 is installed on the opening and clamping control rod 443. Each clamping slider slides along the central control piece 42, and the two ends of the opening and clamping connecting rod 442 are respectively hingedly installed on the opening and clamping slider 441 and the opening and clamping control rope 445. When it is necessary to seal the workpiece pipe between the control rods 443, the opening control rope 445 pulls the opening clamping control rod 443 to move, and the opening clamping control rod 443 drives each opening clamping link 442 to open, and then each opening clamping slider 441 pushes the corresponding plug tube sealing plate 432 to open, and then opens the plug tube annular sealing cloth 431. When the blockage is released, the opening control rope 445 is loosened, the plug tube sealing plate 432 loses support, and the plug tube annular sealing cloth 431 can be automatically retracted.

[0043] Specifically, the side wall of the hollow penetration tube 41 has an anchor rod 411 around which the expansion control rope 445 is wound. The anchor rod 411 is used to fix the expansion control rope 445 during the welding process.

[0044] Specifically, the tracking device 7 is installed at the bottom of the welding gun 1. The bottom of the tracking device 7 is sharp. Specifically, the tracking device 7 is a screw with a sharp bottom. The screw is installed at the bottom of the welding gun 1 through a threaded pair.
