Learn more about the different gases commonly used in general contractors.
N₂
Used for purging and pressure testing pipelines, creating inert atmospheres to prevent oxidation, and in refrigeration applications.
CO₂
Used in welding as a shielding gas, often in combination with argon, and in fire suppression systems. It’s also used for carbonation in certain applications.
O₂
Used in combination with acetylene or other fuel gases for cutting, welding, and brazing operations. It enhances combustion, enabling high-temperature processes.
C₂H₂
Commonly used in oxy-acetylene torches for welding, cutting, and brazing metals due to its high flame temperature.
H₂
Occasionally used in welding processes, particularly for high-temperature brazing and in applications requiring reducing atmospheres.
C₃H₈
Utilized for heating, cutting, soldering, and powering certain types of equipment. It is also used in portable heaters to warm construction sites during cold weather.
Ar
Frequently used as a shielding gas in welding, especially in TIG (Tungsten Inert Gas) and MIG (Metal Inert Gas) welding, to protect weld areas from contamination.
He
Sometimes used as a shielding gas in specialized welding applications, particularly for non-ferrous metals.
