What is TIG or GTAW welding?

What is TIG or GTAW welding? Its operation, use cases, and the necessary equipment to start with this technique.

Did you wonder which machine is used to weld aluminum or how to weld stainless steel? If you've ever seen those almost artistic weld seams with enviable perfection, you were surely appreciating a job done using this process that is ideal for special sight stitching projects.

What is TIG welding

In principle and to avoid confusion, it is valid to clarify that it is usually called both TIG (tungsten inert gas) and GTAW (gas tungsten arc welding).

The best TIG welder has the characteristic of using a permanent tungsten electrode and gaseous arc protection. This electrode does not add material to the weld or is consumed, although it has minimal wear and must be replaced from time to time.

The torch or torch

It is the last link in the circuit. It is the manual tool that allows the control of the arc.

There are different tungsten alloys for each specific use and diameters according to the current of work. To learn more, we recommend reading the special article on tungsten electrodes where you will learn, for example, what type of electrode is used to weld stainless steel, aluminum, etc.
