What Is The Difference In Mig And Tig Welding?

Welding is a highly skilled technique used to bond metal materials or components of metal together. It is used in many industries and applications and provides significant cost savings in manufacturing processes worldwide.

While there are a variety of welding techniques, the two most common types of welding are MIG (Metal Inert Gas) and TIG (Tungsten Inert Gas). While both welding techniques achieve a similar end-result, there are distinct differences between the two. Here we discuss the main differences between MIG and TIG in terms of how they heat metal, the level of skill required to work with them, and their welding power needs.

We explore the current global prevalence for MIG and TIG welding, with key facts and figures. With 69% of the world’s two million welding workers being employed in China and 71% of the world’s four million tonnes of welding consumables being used in the United States– understanding the differences between MIG and TIG welding will provide valuable insight into welding processes everywhere.

What is the Difference in MIG and TIG Welding?

Welding is a process used for connecting pieces of metal that involves the application of heat and a filler material.

There are several different types of welding and two popular methods of welding are MIG and TIG welding. This article will explain the differences between these two methods so readers will better understand the nuances between MIG and TIG welding.

What Is MIG Welding?

MIG (Metal Inert Gas) welding uses an arc to weld pieces of metal together. This process makes use of an electrode wire, which is comprised of metals like aluminum and steel, to create heat that melts the metals to be joined.

The melted metals will then be joined by the electrode wire to create a strong bond. MIG welding is less difficult than some methods and it generally produces a cleaner finish than other types of welding.

Advantages of MIG Welding

  • Can be used by both inexperienced and experienced welders.

  • Welds faster than most welding techniques.
  • Produces a cleaner finish.

What Is TIG Welding?

TIG (Tungsten Inert Gas) welding is another popular welding process that is used to weld metals and other materials together. This technique is more complex than MIG welding and requires more skill to complete correctly.

The process involves the use of a tungsten electrode. This electrode generates an electric arc between the metals to be joined and helps to melt the metals to form a bond. The tip is protected from oxidation by a shielding gas and additional filler material is often used during the process.

Advantages of TIG Welding

  • More precise and adjustable than other welding techniques.
  • Can be used to weld a variety of materials.
  • Produces high-quality welds with a very clean finish.

MIG vs. TIG welding

Though both TIG and MIG welding can be used to successfully weld metals and other materials, there are key differences that should be considered when deciding which technique to use for a particular project. MIG welding is the faster option and is more suitable for inexperienced welders, while TIG welding is more precise and adjustable and produces better quality results. TIG welding is often used for welding aluminum and other specialized metals, while MIG is better suited to steel. The type of material and the desired end result should be taken into consideration when deciding which welding method to use.


Both MIG and TIG welding can be used to join metals and other materials in myriad applications. The type of welding used should be based on the material being welded and the desired results. MIG welding is a faster method and is better suited to steel, while TIG welding is more precise and can be used to weld a variety of materials, particularly aluminum. No matter which technique is chosen, it is important to select the right equipment and follow all safety protocols.
