TIG Process (GTAW)

The Tungsten Inert Gas (TIG) welding process, also known as Gas Tungsten Arc Welding (GTAW), is a welding process that uses a non-consumable tungsten electrode to create the weld. Here is a basic guide to the TIG welding process:

1. How Does TIG Welding Work?

TIG welding works by creating an electric arc between the tungsten electrode and the workpiece, which heats the metal and causes it to melt. A filler metal can also be added to the joint if necessary. The tungsten electrode remains non-consumable, which means it does not melt and is not added to the weld.

2. Advantages of TIG Welding

TIG welding has several advantages over other welding processes:

3. Disadvantages of TIG Welding

TIG welding also has some disadvantages:

4. Applications of TIG Welding

TIG welding is commonly used in industries such as aerospace, automotive, and electronics, as well as for custom and artistic welding projects. It is often used for welding thin materials and for producing high-quality welds that require minimal post-weld finishing.


The TIG welding process is a versatile and high-quality welding process that requires skill and specialized equipment to perform effectively. By understanding the basics of TIG welding, you can determine if it is the right welding process for your project.
