What is Gas Tungsten Arc Welding (GTAW)?

Gas Tungsten Arc Welding (GTAW), also referred to as TIG welding, is an arc welding process that uses a non-consumable tungsten electrode to produce the coalescence of metals.

What is the gas tungsten arc welding process?

The process involves heating the metals with an electric arc between the tungsten electrode and the workpiece. Shielding is usually provided by an inert gas, such as argon, or a gas mixture. Pressure is not used in GTAW, and filler metal may or may not be used.

Advantages of GTAW

The advantages of GTAW include:

  • the ability to produce high-quality welds,
  • the ability to weld metals of different thicknesses,
  • and the ability to weld metals with poor weldability.

Disadvantages of GTAW

The disadvantages of GTAW include:

  • the high cost of the equipment,
  • the need for skilled operators,
  • and the slow welding speed.

What kind of welding is GTAW?

GTAW is a type of arc welding. Arc welding is a welding process that uses an electric arc to create coalescence between metals. GTAW is sometimes referred to as TIG welding.

What gas is used in GTAW welding?

The gas used in GTAW welding depends on the metals being welded and the desired result. Inert gases, such as argon, are often used to prevent oxidation of the weld metal.

Gas tungsten arc welding applications

GTAW is commonly used to weld stainless steel, aluminum, and magnesium. It can also be used to weld nickel alloys, titanium, and other non-ferrous metals.
