Welding, also known as fusion welding, is a manufacturing process and technology for joining metals or other thermoplastic materials such as plastics by means of heating, high temperature or high pressure.During welding, cool the welding torch to prevent the high temperature of the torch.Cooling mode: air cooling and water cooling.
Water cooling torch
The torch is cooled by circulating water. The water-cooled welding gun transmits the coolant to the heating part of the gun neck through the water circulation system and then transfers the heat back to the water tank for cooling.
Water-cooling welding gun provides more power and is suitable for welding large thick metal continuous operation; And high efficiency, and can reach 100% temporary load rate. It has the characteristics of durable and good cooling effect. At the same time, the price of a water-cooled welding gun is higher than that of an air-cooled welding gun.
Air cooling torch
Low-temperature gas is injected from the back of the welding gun, and the gas is ejected from the mouth of the welding gun to take away the heat during welding while cooling the head of the welding gun.
The light air cooling welding gun is suitable for non - continuous, welding work intensity is not small current thin parts welding. It has the characteristics of high precision and a small heat-affected area. But air-cooled welding gun is not suitable for high current, more suitable for small current welding.
How to choose welding torch?
1.Price
In terms of price, water-cooled welding guns are about 50% more expensive than air-cooled ones on average. In addition, the installation of a water-cooling system requires additional expenditure, and the welding torch, as a vulnerable part, is part of the ongoing operating costs.
2. Welding current
Generally speaking, the air cooling welding gun can be selected when the welding current is less than 180A and the welding is not sustainable. The influence of the heat generated by the welding current on the welding gun head can be cooled by the air convection around the welding gun, and the welding nozzle will not be damaged by overheating. However, when the welding current is more significant than 180A, the heat generated by the larger current cannot be rapidly cooled through the convection mode of air around the welding gun. At this time, the water-cooled welding gun can be used to cool the welding gun through the circulating water system rapidly. In addition, a high-power industrial tungsten argon arc welding gun, the use of a more complex water-cooled welding gun, because water cooling can reduce the loss of tungsten and other wearing parts and arc column stability. Suitable for welding thick workpieces and high current continuous welding.
At present, yunhua intelligent use of air cooling welding gun mainly yunhua welding gun and global welding gun.Yunhua welding gun is independently developed and produced by Yunhua Intelligent. It adopts high-strength torsion-resistant and wear-resistant cable, high-quality copper wire core, and has the patent of anti-collision technology invention.Its anti-collision device is fast and has high repeatable positioning accuracy.The global welding torch brand is a well-known brand in China, and has passed ISO-90014-2000 international quality certification and national CCC certification, which can meet most welding needs.
When welding heavy metal, use water cooling to cool the torch.Yunhua smart use yunhua welding gun, global welding gun, Telma welding gun, Apollo welding gun and other brands of welding gun.In addition, customers can choose the designated brand welding torch according to their own needs.
