What Is Gtaw Welding?

As one of the most commonly used welding processes, Gas Tungsten Arc Welding (GTAW) is an essential component of the welding industry. As a manual process, GTaw welding is a low-cost, versatile process — it has been used in the manufacturing of airplanes, cars, and ships since its invention in 194

GTAW is favored for its ability to be used in many types of materials and configurations, and is even capable of achieving high precision results. According to the Bureau of Labor Statistics, the demand for skilled GTaw welders is expected to grow by 8% through 202 With the complex nature of GTAW welding, understanding the basics of this process is essential for producing quality welds.

So, what is GTaw Welding?

What is GTAW (TIG) Welding?

GTAW, also known as TIG (tungsten inert gas) welding, is an arc welding process that uses a non-consumable tungsten electrode to produce the weld.

It is usually used for materials such as aluminum, magnesium and stainless steel, as it produces a higher quality weld with better control over the welding parameters.

The Basics of GTAW Welding

GTAW welding is a shielded welding process that requires the use of a shielding gas around the weld puddle. The shielding gas helps to protect the weld from the atmosphere, allowing for a high level of control over the welding process.

The welding arc is created by the electrical current that flows between the tungsten electrode and the work piece.

Advantages of GTAW Welding

GTAW welding offers several advantages over other welding processes:
  • Produces high quality welds with excellent control over weld parameters.
  • Can be used on a wide variety of metals, including aluminum and stainless steel.

  • Provides high level of control over the weld.
  • Welds with minimal distortion and spatter.

  • Produces welds that are more aesthetically pleasing.

Disadvantages of GTAW Welding

GTAW welding is a slow process, as it requires a great deal of skill and precision. Additionally, GTAW welding is expensive due to the need for special equipment, shielding gases and other consumables.


GTAW welding is an effective arc welding process that produces high quality welds with excellent control over weld parameters. It is used for welding materials such as aluminum, magnesium and stainless steel and offers numerous advantages over other welding processes.

However, it is slow and expensive.
