TIG welding (Tungsten Inert Gas Welding) is an inert gas arc welding method that uses tungsten electrode as a non-consumable electrode while adding an inert gas such as argon or helium as a shielding gas to prevent the arc and weld area from being affected by airborne impurities. TIG welding can be used to weld a variety of metal materials, especially stainless steel, aluminum, magnesium, titanium and other materials that are difficult to weld.

TIG：

1. High quality, without spatter, porosity and other defects, and the surface is smooth and clean, and there is no need to clean it.

2. There are no pollutants such as smoke and dust, harmful gases and other pollutants during the welding process, which is beneficial to the environment and human health.

3. The welding current is small, the heat affected zone is small, the deformation and stress are small, and it is suitable for the welding of thin plates and precision parts.

4. It can realize full-position welding, and the operation is flexible and convenient.

5. Single-sided welding and double-sided molding can be realized, saving materials and man-hours.
