At WestBay, we understand that many different gases play a critical role in welding. One of the most versatile and widely used gases in manufacturing and fabrication is carbon dioxide (CO₂). While commonly associated with beverages and refrigeration, CO₂ also plays a vital role in metal fabrication as a shielding gas.
A Multi-Industry Workhorse
Carbon dioxide is used in the food and beverage industry as a cooling, chilling, and freezing medium, and also plays a key role in carbonating beverages. In the entertainment and sports industries, it’s used as a paintball propellant, and in safety systems, CO₂ is essential in fire suppression applications.
This wide range of uses speaks to the gas’s reliability, cost-effectiveness, and availability—making it a go-to solution across many sectors, including welding.
CO₂ as a Shielding Gas in Welding
In metal fabrication, carbon dioxide is most commonly used as a shielding gas in MIG (Metal Inert Gas) welding. When molten metal is exposed to the air during welding, oxygen and nitrogen can contaminate the weld, leading to porosity, cracking, and weak joints. CO₂ acts as a protective blanket over the weld pool, displacing atmospheric gases and ensuring a cleaner, more stable arc.
While pure CO₂ can be used on its own, it’s also frequently blended with other gases like argon to balance penetration, spatter, and weld appearance. It’s especially popular in heavy-duty welding applications where deeper penetration is needed, such as in structural steel and industrial fabrication.
