Description

Technical Field

[0001] The utility model relates to the field of submerged arc welding equipment, in particular to a water cooling system of a submerged arc welding conductive device. Background Art

[0002] Submerged arc welding (SAW) is widely used in the production and processing of steel pipes due to its inherent advantages, such as stable welding quality, high welding efficiency, and strong adaptability. However, due to the high welding current, fast welding speed, and continuous welding process, the temperature of the SAW conductive device is relatively high. Especially when welding thick-walled steel pipes, the temperature of the SAW conductive device can rise rapidly and remain at 350°C-400°C. This condition affects welding stability and may even cause the conductive device to burn out, requiring welding to be stopped and cooled before continuing. This seriously affects welding efficiency and increases production costs. Utility Model Content

[0006] Wherein, the cooling pipeline is U-shaped or spiral-shaped.

[0007] Preferably, the water pump is a variable frequency water pump capable of adjusting the flow rate of the pumped liquid.

[0008] The radiator includes a rectangular frame, a serpentine fin tube and a fan. The serpentine fin tube and the fan are both installed in the rectangular frame.
