 Three advantages of using ceramic nozzles

 

1. The ceramic nozzle with simple structure and suitable for mass production, its design structure. It is a push-wire type welding gun nozzle for gooseneck type welding torch; it is a wire-type welding gun nozzle for pistol type welding torch. Since the structure of the nozzle is simple, the arrow is easy to manufacture. In the nozzle production process, it is more than ten times more efficient than the copper nozzle, which is very suitable for the production of a large number of defects.

2. Insulation is good and easy to use. Because the ceramic nozzle is insulated and non-conductive, in the process of welding, unlike the copper nozzle, once the metal splash gradually builds up on the inner wall and the wire is connected, the nozzle touches the workpiece. A short circuit occurs, causing a spark to burn out. The structure of the ceramic nozzle is small and light, which is convenient for the welder to observe the baking pool and facilitate the operation, and is beneficial to improving the quality of the weld and reducing the labor intensity of the worker.

3. Less splashing and easy to remove slag Because the copper nozzle receives the heat radiated from the gun body and the heat radiated directly by the welding arc, the temperature rises rapidly, and the material softens, which easily causes nozzle deformation. At this point, it is slightly touched, and the nozzle mouth is irregularly rounded or polygonal. What is more serious is that the inner wall of the nozzle is easy to adhere to the splash and accumulates in a pile, blocking the air passage and deteriorating the gas protection performance. Scraping off the splashing slag on the inner wall of the nozzle is both laborious and affects production efficiency. When the ceramic nozzle is used, the effect is completely different, and it has no heat softening phenomenon. It is not easy to stick to slag.

Whether using a push-wire welding torch or a wire-wound welding torch, the nozzle material used is changed from copper to ceramic. The use of the field shows that the advantages of using ceramic nozzles are many and the effect is good.
