Applications of CO2 gas

The versatility of CO2 gas makes it invaluable across various industries. Here are some of the most common uses:

  • Welding: CO2 is widely used in MIG (Metal Inert Gas) welding due to its cost-effectiveness and ability to produce strong welds in steel. It’s also an essential component in TIG (Tungsten Inert Gas) welding for shielding purposes.

  • Beverage carbonation: CO2 adds fizz to sodas, beer, and sparkling water. It’s a staple in the food and beverage industry for enhancing product quality and shelf life.

  • Greenhouse enrichment: Farmers and horticulturists use CO2 to promote plant growth, enhancing crop yield and efficiency.

  • Dry ice production: Solid CO2, or dry ice, is used for refrigeration, shipping perishable goods, and even creating fog effects in entertainment.

  • Lasers: High purity carbon dioxide is widely used in CO2 lasers as well as in laboratories.

MIG vs. TIG Welding with CO2

For welders, choosing the right gas is crucial. Here’s how CO2 performs in MIG and TIG welding:

  • MIG CO2 welding: CO2 is a cost-effective option for MIG welding, particularly for steel. While it produces a slightly rougher weld compared to argon or mixed gases, it is widely used due to its affordability and strong weld characteristics.

  • TIG CO2 welding: While TIG welding typically uses inert gases like argon, CO2 can be used as a shielding gas in specific applications. However, it’s less common due to the precision and smooth finish required in TIG welding.

Coregas offers both CO2 and argon gas solutions, ensuring welders have access to the right gas for their needs.
