What is Tig Welding?

Welding is the technique of joining metals having different techniques and types. Tig welding is one of the finest types of welding to join the harder metals. It is a method that requires extra precision and accuracy. That’s why it is a little bit costly as compared to others. 

Also, it is the most adaptable welding technique because it can join materials of any size and metal variety. TIG is used by artists for their works as well as in fields that demand fine, precise, and aesthetically pleasing welds.

To know more about what is Tig welding, you have to come up with me!


What is Tig Welding? 

Many welders refer to TIG welding as gas tungsten arc welding (GTAW). It is a type of welding that uses an electrical spark and TIG electrodes, which don’t melt. Unlike MIG welding which uses filler material, TIG welding only requires fusing the materials.

TIG welding is a very adjustable technique that can be employed on thinner steel plates. Additionally, it performs effectively with materials like stainless steel and aluminum. But it is ineffective when welding with plastics or other metals that cannot withstand extreme heat.

The capacity to produce complicated metal parts with little waste products is the major advantage of Tig welding. The final product will appear accurate and clear after welding. 

Also, it makes it attractive for numerous uses in the manufacturing of cars, aviation, and other related businesses. 

When the two elements are consistent with the fillers, this method of welding also enables the usage of two distinct elements.

Structure of the Tig Welding: 

Mains connection

Power source


grounding cable

Welding torch

Ground terminal


Filler metal

Shielding gas

How does Tig Welding Works?

To start the Tig welding operation, you will ignite the steel rod with light and place it near the elements that you will weld. After this first phase, you will have to insert the filler cable. 

In this process, the two different metals will be heated by an electrical arc that has formed between them. Due to the semi-alloy composition of the filler material, it dissolves at a low temp. Its temperature will be different compared to the temperature in the surroundings.

After that, it combines with these components to form a solid connection. This robust connection will maintain everything in position. As an alternative to air, radon or carbon dioxide gas will be used for TIG welding.  

It offers more shielding against impurities that can be present in the air even after your workplace has been well cleansed. Purified tungsten filaments are used by many welders because they need less power to function.

TIG welding needs a strong hand and effective coordination, particularly when dealing with complicated or light items. Additionally, it typically requires more time than other welding techniques. 

Despite these difficulties, a lot of welders find this procedure pleasant. It is because it allows them to be innovative and deliver consistent results.


Suitable Metals for Tig Welding

Stainless steels, aluminum, and nickel metals, and thin sheets of aluminum and stainless steel are the metals that are highly preferable to utilize in TIG welding. 

For sheet widths under 4 mm, a mechanical wire feeder can reach cost-effective welding rates. The cost-effectiveness is good for bigger sheets, and the TIG technique is only advised for welding the root pass.

How does Tig welding compare to Other Techniques? 

Tig welding provides a more accurate impact on the final output and it is regarded as a “high-end” method of welding. When compared, MIG or flux-cored arc welding delivers less precision and can result in annoyance. 

Without much practice, these procedures are simpler for novices to understand. A thorough understanding of metals is also necessary for TIG welding. It is good to determine which filler wire to use with which alloy. This will allow you to get the desired level of precision in the final result.

What are the Advantages of Tig Welding? 

Below are the major advantages of Tig Welding. Let’s have a look at them; 

TIG welding has many advantages as compared to other conventional welding techniques. Because it uses an electrical discharge instead of a flame, it has good control to deal with thinner metal sheets. 

It helps to create less dispersion than certain other techniques. These parts also have the potential to cool more quickly when you are welding them.

Another benefit of TIG welding is that it produces few residual wastes or particles. They could harm human health or the environment. This makes it perfect for environments like food processing industries and healthcare institutions, where sanitation is critical. 

Additionally, when you begin by selecting a gas with a low oxygen content, it does not produce any emissions while performing this type of task.

What are the Disadvantages of Tig Welding? 

Below I am going to discuss the disadvantages of Tig welding: 

The complexity of TIG welding is one of its main drawbacks. Many newcomers find it challenging to perform even the simplest welds. It is because this welding demands additional accuracy and precision in your hand and arm operations. This could be challenging for many people who just started welding. 

Due to the usage of specialized equipment and filling cord, it is more expensive than some other forms of welding. As with other welding techniques, you do not require the use of filling material, so this is a little expensive. 

Additionally, dirt and other impurities can affect your final result. That’s why you must cleanse your workspace before starting the project and after using this approach.


TIG welding is a fantastic option for many applications. But it needs a different method than the majority of other welding techniques. In this article, I have clearly explained “what is Tig welding” and how it works. Also, you will get to know what the advantages of Tig welding are. 

Before starting any large project, you must understand how to accomplish the task correctly. When utilizing arc welding equipment, you must always take care to prevent injury or harm to the area surrounding your residence.
