What Are the Application Scenarios of Argon Cartridge as a Rare Gas?

Argon Cartridge, as a special high-pressure container for storing and transporting argon, is widely used in many industrial and commercial fields.

1. Physical and chemical properties of argon

Argon is a colorless, odorless, inert gas with very stable chemical properties. It has extremely low solubility and high ionization potential at room temperature and is not easily contaminated by other gases or substances. At the same time, the density of argon is about 1.4 times that of air, so it can effectively extinguish the flame. In welding, since the welding area is extremely susceptible to contamination by oxides or other impurities in the air, a stable and pollution-free gas is needed to protect the purity of the welding area, and Argon Cartridge is an ideal gas choice.

2. The role of argon in welding

Prevent oxidation reaction: In welding, metals at high temperatures easily react with oxygen in the air to form oxides. The presence of oxides can lead to welding defects such as impure color, looseness, pores, and cracks. The inertness and density advantages of Argon Cartridge can effectively isolate air and other gases, prevent oxidation reactions, and thus ensure the quality of the weld.

Keep the weld area dry: During welding, since the metal itself or the welding wire contains moisture or volatile solvents, in order to avoid welding bubbles or defects, it is necessary to keep the welding area dry by heating and protective gas. At this time, using Argon Cartridge as a protective gas can effectively increase the gas pressure and inhibit the volatilization of moisture and other solvents during the welding process, thereby ensuring the quality of welding.

Protecting the arc: In welding, the arc is a high-temperature gas discharge, and its heat and energy can easily cause damage to the surrounding metal. Using argon as a protective gas can form a stable gas environment during the arc process, thereby preventing the arc from damaging the metal.

Metal heat treatment: In the process of heat treatment such as metal quenching and tempering, the use of argon can isolate the metal from contact with the outside air, ensure that the metal surface is not contaminated, and maintain the original performance and appearance of the metal.

3. Other applications of argon

Argon can produce a stable purple light in a light bulb, so it is widely used to manufacture various electric light sources. Rare gas discharge lamp: Using the discharge phenomenon of argon in a high-voltage electric field, colorful and high-brightness rare gas discharge lamps can be produced, such as argon arc lamps, which are often used for lighting decoration in large squares, stadiums and other places.

Protective atmosphere for chemical reactions: During chemical reactions, using Argon Cartridge as a protective atmosphere can prevent the reactants from reacting with oxygen or other impurities in the air, ensuring the accuracy of the experimental results.
