TIG welding is the process of joining two metals together using a tungsten electrode. There are many moving parts to this process, so it takes a skilled professional to produce a quality weld, especially for commercial or industrial projects. However, it may be interesting for those in need of TIG welding services to understand a bit about how the process works. During these projects, welders use various types of gas to protect their welding arc and produce quality finishes. Here’s what you should know about this part of the welding process.

A Guide to Gasses & TIG Welding

How Gasses Are Used

In the TIG welding process, gasses are used as a shield to protect the welding area from materials that can negatively impact the process, like water vapor or oxygen. The excessive heat and spatter that comes from the process can sometimes lead to oxidation if the welding arc is left exposed. Since the gasses used in this process are fairly dense, the air is not able to penetrate the surface, keeping the actual welding area completely secure.

Commonly Used Types of Gasses for Various Materials

Argon and helium are the most common types of gasses used in TIG welding. Both of these gasses can work for common TIG welding materials, including steel, aluminum, and nickel. Welders can opt for one or the other, or a combination of both depending on the heat and precision needs. Argon usually provides better puddle control for precision welding, while helium is often preferred for high heat welding projects.
