VI. Applications of Argon:
Argon is a rare gas that finds extensive application in industry. It is highly inert, neither combustible nor supportive of combustion. In aircraft manufacturing, shipbuilding, the atomic energy industry, and mechanical engineering, argon is often used as a shielding gas during welding of special metals—such as aluminum, magnesium, copper and their alloys, as well as stainless steel—to prevent the welded components from oxidizing or nitriding in air.
1. Aluminum industry: Used to replace air or nitrogen to create an inert atmosphere during aluminum production; assists in removing unwanted soluble gases during degassing; and helps eliminate dissolved hydrogen and other particulates from molten aluminum.
2. Steelmaking: Used to displace gases or vapors and prevent oxidation in the process; employed to stir molten steel in order to maintain a constant temperature and uniform composition; aids in the removal of unwanted soluble gases during degassing; as a carrier gas, argon can be used in chromatographic analysis to determine the composition of samples; argon is also utilized in the Argon-Oxygen Decarburization (AOD) process employed in stainless steel refining, with the goal of removing carbon monoxide and minimizing chromium loss.
3. Metalworking. Argon is used as an inert shielding gas in welding; it provides oxygen‑ and nitrogen‑free protection during the annealing and rolling of metals and alloys; and it is also employed to flush molten metal in order to eliminate porosity in castings.
4. Welding shielding gas. During the welding process, argon serves as a shielding gas, preventing the burn-off of alloy elements and the resulting welding defects. This simplifies and makes the metallurgical reactions during welding easier to control, thereby ensuring high-quality welds.
5. Other applications: electronics, lighting, argon plasma coagulation, and more.
7. Important Notes:
1. Argon should be stored in a well‑ventilated, dry, and cool warehouse, away from heat sources and ignition sources, protected from direct sunlight, and cylinder bottles must be secured to prevent tipping.
2. Argon gas in cylinders is high‑pressure compressed gas and must be depressurized before it can be used.
3. Argon has a specified shelf life; it should be used within that period. Argon that is nearing its expiration date must be sent to the relevant authorities for safety inspection, and can only continue to be used after passing the inspection.
4. When using argon gas until the tail gas is exhausted, maintain a residual pressure of 0.5 MPa in the cylinder; the residual pressure must not fall below 0.25 MPa. In addition, the cylinder valve should be closed to ensure gas quality and operational safety.
5. Argon gas should be stored, transported, and used in a categorized manner; flammable gases must not be stored together with oxidizing gases, and leak emergency response equipment should also be provided.
6. When using argon gas, avoid sources of ignition, oils, direct sunlight, rough handling, and impact.
7. During the storage and transportation of argon gas, handle it with care to avoid collisions and excessive temperatures. It is advisable to equip argon cylinders with safety caps and install vibration‑resistant rubber rings on aluminum alloy doors and windows.
8. If argon gas work is required, you must wear protective equipment such as air respirators and oxygen masks.
9. In the event of an argon gas leak, promptly evacuate the contaminated area, put on a respirator or frost protection gear, and, if conditions permit, move the leaking cylinder to an open, safe location and secure it there.
