Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to a argon arc welding torch with a cooling function and a welding device having the argon arc welding torch. Background technique [0002] On the basis of ordinary arc welding, argon arc welding technology uses argon gas to protect the metal welding material, and through high current, the welding material is melted into a liquid state on the substrate to be welded to form a molten pool, so that the metal to be welded and the welding material reach A welding technology of metallurgical combination, because argon gas is continuously supplied in high-temperature fusion welding, so that the welding material is not in contact with oxygen in the air, thereby preventing the oxidation of the welding material, so it can weld stainless steel and iron metal metals. The argon arc welding equipment consists of welding machine, welding torch, control box, water and electricity, ground ...

AI Technical Summary

Problems solved by technology

[0004] The gas flow of the argon arc welding torch in the prior art is difficult to control, the heat dissipation point of the welding torch is far away from the heat point, the heat dissipation is poor, the tungsten electrode is severely ablated, the arc cannot be accurately controlled, and the operation is also troublesome; due to structural limitations, the energy density of the arc It cannot be further improved, making it difficult to improve the welding efficiency, the welding quality is affected, and the adaptability of welding materials is also affected

In addition, there is still a lack of technology in the prior art that can effectively cool the heating point of the gun body, which makes the temperature of the heating point of the gun body higher, which is not conducive to prolonging the service life of the insulating material and is not conducive to safe operation
