TIG welding

TIG (Tungsten Inert Gas) welding is one of the most commonly used welding processes by welders. But, do we really know what it consists of, how it is used or what its advantages and disadvantages are? For all those who are not completely clear about it, we recommend you to read this post where we will clear all the doubts about TIG welding.

What is TIG welding?

In the TIG welding process, the current that is necessary for the fusion zone is supplied by a tungsten electrode, one of the main components of this welding process. From this tungsten electrode, the arc comes out, which heats the material to be welded until it becomes liquid. The weld pool is protected by an inert gas (usually Argon gas) that comes out of the nozzle of the TIG torch.

This welding process guarantees high quality weld seams, being one of the fusion welding processes that produce precise seams with the best visual aesthetics.

When and what is TIG welding used for?

TIG welding is used when we want to achieve a high quality seam without spatter. It is ideal for work on thin metals.

TIG welding usually produces a very aesthetic seam, which is why it is often the preferred method for welding stainless steel kitchen furniture, such as a bar counter or shelves in a restaurant kitchen. It is also a widely used method for welding bicycle or motorbike frames.

This process being so meticulous and aesthetically beautiful makes it particularly demanding and we have to be really concentrated when doing it.

Some of the common uses of TIG welding include:

  • Aerospace industry

  • Automotive

  • Shipbuilding

  • Art and Sculpture

  • Food Industry

  • Pipes and Tubes

  • Nuclear Industry

Advantages and disadvantages of TIG welding


  • Fluxing and post soldering cleaning is not strictly necessary.
  • Easy to handle and suitable for soldering in all positions.
  • This solder does not spatter during the process.
  • The results are very satisfactory with high quality welds.
  • TIG welding can be automated by controlling the gun mechanically.
  • Generates little smoke


  • The speed of the welding process is low.
  • A high level of experience and skill is necessary for correct execution.
  • It is not recommended for very thick parts.
