Argon is a colorless, odorless, and non-toxic rare inert gas with stable chemical properties; it does not burn or support combustion. It is produced from air through a cryogenic air separation and rectification process. Qiaoyuan Gas, relying on its own air separation base, can supply industrial pure argon, high-purity argon (5N), and liquid argon, strictly implementing the national standard GB/T 4842-2017, with full-process online testing and stable purity. It is compatible with multiple gas supply modes including cylinders, dewars, cryogenic storage tanks, and tanker trucks, serving industries such as welding, metallurgy, semiconductors, photovoltaics, laboratory analysis, and lighting.
Main Application Scenarios
- Welding Processing: Shielding gas for TIG welding, used for stainless steel, aluminum, magnesium, and titanium alloy welding, isolating air to prevent weld oxidation and nitriding, improving weld formation and mechanical properties.
- Metallurgical Smelting: Refining and stirring of molten steel, protective atmosphere for non-ferrous metal smelting, removing impurities from the melt, and improving the quality of finished metal products.
- Electronics and Semiconductors: Semiconductor etching, deposition, purging and displacement; carrier gas for analytical instruments such as ICP spectrometers; protective atmosphere for photovoltaic manufacturing.
- Lighting and Optoelectronics: Fill gas for bulbs and lamps; excimer laser operation.
- Heat Treatment: Inert protective atmosphere for annealing and heat treatment of stainless steel and special metals.
