FAQs

How much is welding gas?

The cost of welding gas will depend on your planned use, the type of welding gas, and the amount that you require. To discuss your welding gas needs, contact the Supagas team for a quick quote.

Are welding gas bottles made of steel?

Most welding gas bottles are fabricated from steel, because the material is durable and safe for commercial use.

What gas is used for welding?

A range of gases are used for welding; the right one for you will depend on the application. Argon is the most commonly used gas, as its properties make it versatile and suitable for use in both TIG and MIG welding. Helium, carbon dioxide, oxygen, nitrogen and hydrogen are often mixed with other gases such as argon—for greater arc stability and higher quality welds. For oxy-fuel welding, acetylene is often chosen for its highly combustible nature.

What gas is needed for aluminium MIG welding?

Argon is the most common choice for aluminium MIG welding. As a shielding gas for MIG, argon is an inert gas: meaning it will remain stable throughout the welding process, while protecting the weld from contaminants. Argon helps prevent porosity and spatter, resulting in higher quality aluminium welds.

What gas to use for TIG welding aluminium?

When TIG welding aluminium, argon is most suitable. Aluminium is a non-ferrous material, which means it requires pure argon gas. Argon is a non-inert gas, which makes it stable through the TIG welding process. This results in excellent TIG welds.
