Welding mixed shielding gas is designed to improve the quality of welds. The gases required for the mixed gas are also the common welding shielding gases such as oxygen, carbon dioxide, argon, etc. Using mixed gas instead of single gas for welding protection has a good effect of significantly refining molten droplets, promoting weld smoothness, improving forming, and reducing the rate of pores, and is very popular in welding, cutting and other industries.
Currently, the more commonly used mixed gases can be divided into binary mixed gases and ternary mixed gases according to the type of mixed gases.
The ratio of each component in each type of mixed gas can vary in a large range, which is mainly determined by many factors such as welding process, welding material, welding wire model, etc. Generally speaking, the higher the requirements for weld quality, the higher the purity requirements for the single gas used to prepare the mixed gas.
