Welding Gas

Welding gas includes shielding and fuel gases used to protect the weld pool, stabilize the arc, and improve weld quality in industrial welding and cutting processes. The right gas selection ensures clean welds, proper penetration, and consistent performance.

BluNet supplies high-purity welding gases and optimized gas mixtures for MIG, TIG, MAG, and oxy-fuel applications, supporting efficient and reliable operations.

Types of Welding Gases

Inert Shielding Gases

• Argon (Ar) – Stable arc, smooth finish, widely used in TIG and MIG welding
• Helium (He) – Higher heat input for thick sections and faster welding

Active Gases

• Carbon Dioxide (CO2) – Cost-effective, deep penetration for steel welding
• Oxygen (O2) – Improves arc stability and weld bead wetting (low ratios)

Gas Mixtures

• Argon + CO2 – Standard MIG welding gas
• Argon + Oxygen – Better arc control and appearance
• Argon + Helium + CO2 – For stainless steel and alloys

Fuel Gases

• Acetylene (C2H2)
• Propane / Propylene
