Application Areas:
Argon is a rare gas widely used in industry. It is very inactive and can neither burn nor support combustion. In aircraft manufacturing, shipbuilding, atomic energy industry and mechanical industry, argon is often used as welding shielding gas for welding special metals such as aluminum, magnesium, copper and its alloys and stainless steel to prevent the welded parts from being oxidized or nitrided by air.
In metal smelting, oxygen and argon blowing are important measures to produce high-quality steel. The argon consumption for each ton of steel is 1 to 3 m3. In addition, argon is also needed as a protective gas for the smelting of special metals such as titanium, zirconium, and germanium, as well as in the electronics industry.
