What Is Argon Used For In Welding?

Introducing the world of Argon and welding: Did you know that Argon gas is one of the most widely used gases in welding, that around 70% of welding tanks contain Argon gas and that it’s used in both MIG and TIG welding? This article will delve into the mysteries of Argon and welding, and answer the question – what is Argon used for in welding? We’ll explore the common uses of Argon in welding, how it facilitates welding processes and how it can be used to produce welds of exceptional quality.

Read on to discover the wonders of Argon and welding.

What is Argon Used For In Welding?

Welding is a process in which two pieces of metal or plastic are joined together by melting them together at a high temperature. This process is essential to the construction and maintenance of everything from bridges and ships to home and automotive repairs.

Argon is a colorless and odorless gas that is often used in welding, and it can greatly improve the outcome of the welding process.

Why is Argon Used for Welding?

Argon is used for welding for a number of reasons. The primary purpose of argon in welding is to act as an inert gas shield. Argon is an inert gas, meaning it does not react with the metals that are being welded.

By surrounding the weld area with argon gas, it prevents other air particles from entering the weld area, which could damage the weld. In addition, argon can be used to cool the weld area, help prevent oxidation, and increase the strength of the welds.

What Types of Welding Require Argon?

Argon is most commonly used in a type of welding called MIG (metal inert gas) welding or (GMAW – gas metal arc welding). MIG welding is a type of welding that uses electricity and a consumable wire electrode to join metals or plastics.

The electricity creates an arc between the consumable wire and the metals or plastic being joined, and the argon gas provides a gas shield to keep contaminants away from the weld area.

Are There Other Gases Used in Welding?

Yes, there are other gases that can be used in welding. Helium, carbon dioxide, and nitrogen are some of the more commonly used gases. Each of these gases has different properties that provide unique benefits for specific types of welding.


In conclusion, argon is an essential component in modern welding applications. It helps to shield the weld area from contaminants, cool it down during welding, and improve the strength and appearance of the weld. It can be used in MIG welding and other types of welding. It is important to understand the different factors that go into welding in order to achieve the best results.
