TIG Welding: Definition, Usage, Safety, And Limitations

Last updated: April 9, 2019 By Arvin Reynold

Mostly known as the Gas Tungsten Arc Welding (GTAW). But TIG basically stands for Tungsten Inert Gas. As you can see, the tungsten plays a very important role here.

The welding working process is very simple. The tungsten electrode delivers the current to the welding arc. Here, the tungsten electrode is non-consumable.

Inert gas like argon protects and cool down the tungsten and the weld puddle. In race car fabrication, people apply the TIG welding wearing the proper welding helmet.

Before we go any deeper, let’s watch the explainer video on what is this welding.

After watching the video, I believe you have understood what is TIG welding, right? There is nothing much to explain any further. But we will now talk about its safety issue, usages, and limitations.

TIG Welding Applications

Like MIG welding, the application areas of the TIG welding is very vast. It is mostly used in the following sectors:

  1. Aerospace Industry: For strength and precision, this welding is second to none. That ’s the reason it is widely used in aerospace industry. In both commercial plane and spacecraft industry, TIG welding is hugely used.
  2. Automotive Industry: This industry requires the safe and secure construction of cars. The welding is prominent to do the job that way. It helps the automotive industry to avoid rust. It’s proven that TIG strategy helps the automotive industry to reduce corrosion over time.
  3. Repairing Anything: To repair almost anything, this welding really comes in handy.

Advantages of TIG Welding

Due to the pinpoint control of the TIG welding, it has many advantages that you won’t find in any other welding methods. Here are some of the advantages of TIG welding:

  • When precise welds are required, there is no alternative to this welding.
  • The filler material deposition rates are very lower.
  • If you need to weld dissimilar metal, TIG is second to none.
  • Greater weld puddle visibility.
  • Highly effective to produce results on welding thin material.
  • Greater control of heat during the welding process.
  • You don’t need any flux for this process to work.
  • Great control over heat input.
  • TIG welding can weld more metals and metal alloys than the all available arc welding process.
  • It does not spark or spatter.
  • Affordable cost for the TIG welding services.

TIG Welding Safety

There are many threats associated with this welding like electric shock, radiation, welding fumes, and so on, even if you do it on your portable TIG welding machine. And the worst part is it may happen before or after the welding is done. You must identify such hazards before you start welding. Take preventive measures like wearing welding helmet, leather gloves and jackets, and so on.

Limitations of TIG Welding

You have learned lots of advantages of the welding, but it is not free from some limitations as well. Here are some of its great disadvantages:

  • Lower and slower travel speeds than other welding processes.tig welding
  • Can’t perform well when you weld the dirty metals. It always requires the clean metals to work.
  • Sometimes, lower filler metal deposition rates can be a problem.
  • The UV ray is brighter than any other welding process.
  • Huge practice required to master TIG welding. The skill of hand and eye coordination is greatly required.
  • It requires the use of your 2 hands and 1 leg which leaving you to stand in one leg only!
  • If you work in a confined place where there is no proper ventilation system, the shielding gas may concentrate and displace the required oxygen.
  • The cost of the welding equipment is much higher than other welding solutions.


Briefly, I have covered almost every basic of TIG welding, right? The idea of this article is not to teach you how to TIG weld, but to give you some basic information on it so that you don’t have to start from the level zero. Let me know if you need to know anything more on TIG welding.
