What is Tungsten Inert Gas (TIG) Welding? All You Need to Know

Tungsten inert gas welding, also known as gas tungsten arc welding, produces welds with non-consumable tungsten electrodes. Inert shielding gas protects the electrode and weld area from oxidation and atmospheric contamination. 

In tungsten inert gas (TIG) welding, a non-consumable tungsten electrode is used to create an electric arc between the workpiece and the electrode, fusing metal in the joint area and producing a molten pool of metal.

TIG Welding Applications

TIG welding can be used in a variety of applications where high-quality welds are required. This includes welding aluminium, copper, nickel, magnesium, titanium, and their alloys. TIG can also be used to weld in any position – including flat, vertical, horizontal, and overhead positions – making it ideal for use in a range of industries, such as the aerospace industry. 

TIG welding produces strong, precise welds that can be costly and time-consuming. Welders often TIG aluminum and stainless steel projects because of the high-quality welds it produces. The process is not easy to learn but once mastered; many welders find it the most satisfying method.

The following are the key advantages of TIG Welding:

  • TIG welding is a versatile method that can be used on a variety of materials, including metals that are difficult to weld. It is a precise process that allows for intricate welds to be made with great accuracy. It produces clean, strong welds with minimal distortion.
  • It is a relatively slow process, which results in less heat being applied to the base metal and, therefore, less warping and deformation.
  • TIG welding can be performed in all positions, including vertical and overhead. It produces very little smoke and spatters, making it a cleaner process than other welding methods.

What is AC DC TIG Welder?

Direct current (DC) TIG welding creates a current that flows in one direction only. This is different from AC (alternating current) TIG welding, where the current alternates between positive and negative charges. In general, TIG inverters can weld using either DC or AC/DC power, though there are very few machines that are AC-only.

What Should You Consider When Choosing a TIG Welder?

TIG welding is a popular choice for welders because it produces high-quality, precise welds. When choosing a TIG welder, there are several features to consider. Pulsed welding is a feature that can help to reduce heat input and improve weld quality. Portability is another important consideration, especially if the welder will be used in multiple locations. Some TIG welders also have foot pedals, which can be used to control gas flow and welding speed. High-frequency settings can help to minimize arc interference, and simple controls make it easier to set the welder up for different types of projects. Plasma cutter and stick welding options are also available on some models, which can be useful for welders who need to use both welding processes. By considering these features, welders can choose the best TIG welder for their needs.
