What Gas Is Used For Welding Aluminum?

Welding aluminum is an important process in many manufacturing and engineering businesses. It serves a vital purpose in the production of many items, such as cars, boats and furniture.

But what gas do you use to weld aluminum? Did you know that 6 million tons of aluminum are produced annually, with 78% of that being used for transportation applications? This article will discuss what gas is used when welding aluminum, why it is necessary, and how to ensure the best results.

What Gas is Used for Welding Aluminum?

Welding aluminum is a specialized process that requires choosing the right gas and other materials. Welders have to ensure that the entire process is done accurately to ensure safety and quality.

To understand which gas is used for welding aluminum, let’s look at the three main types of welding aluminum: oxyfuel welding, gas tungsten arc welding, and gas metal arc welding.

Oxyfuel Welding

Oxyfuel welding is often referred to as oxy-acetylene welding.

This type of welding is commonly used for welding aluminum as it provides high temperatures that are essential for metals like aluminum, brass, and steel. Oxyfuel welding requires the use of two gases – oxygen and acetylene.

Acetylene is mixed with oxygen to generate the flame that will be used to heat and fuse the aluminum.

Gas Tungsten Arc Welding

Gas tungsten arc welding is another method used for welding aluminum. This process utilizes an arc which is generated between the tungsten electrode and the aluminum.

The arc is used to heat the aluminum, allowing for a joined weld. This type of welding requires the use of argon or helium as a shielding gas to prevent the aluminum from becoming contaminated with oxygen or nitrogen.

Gas Metal Arc Welding

Gas metal arc welding is often referred to as GMAW or MIG welding. This type of welding is used for welding aluminum and is the most commonly used welding process for this metal. It requires the use of a shielding gas, most commonly argon, to prevent contamination and oxidation of the aluminum.

The shielding gas also helps to stabilize the arc and improve the quality of the weld.


The type of gas used for welding aluminum will depend on the welding process that is being used. Oxyfuel welding requires the use of oxygen and acetylene, gas tungsten arc welding requires argon or helium, and gas metal arc welding requires argon as a shielding gas. Finding the right gas depends on the type of application and the materials being used. It is important to ensure that the right gas is chosen to ensure a clean, safe, and effective weld.
