What Is Tig Welding?

Tig welding is a popular form of arc welding that has been around since the 1930s, with over 6 million welders certified annually world-wide. The technology is now seen in a variety of industrial applications, from aircraft and automotive manufacturing, to medical devices and construction projects. Today, tig welding is used to join together a variety of materials, including aluminum, stainless steel, copper, titanium, and other metals, as well as ceramics and plastics.

In tig welding, an electric arc is used to heat the metal until it melts, allowing the two pieces of metal to be combined. With its various applications and ease of use, tig welding is an incredibly versatile process and an increasingly popular choice among welders.

In this article, we’ll explore what is tig welding, its advantages and disadvantages, and some tips for working with the technology.

What is TIG Welding?

TIG welding (Tungsten Inert Gas welding) is a type of welding which uses a non-consumable tungsten electrode to produce the weld.

It is the most often used welding process because of the quality of the joint it produces. TIG welding is more precise, compared to other welding processes. It is used to weld various kind of metals such as steel, stainless steel, aluminum, nickel alloys and cobalt alloys.

What are the Benefits of Using TIG Welding?

  • High-Quality Welds – Produces high-quality welds with virtually no post-weld cleanup.

  • Precision & Control – Solidifies weld joints at a precise and controlled rate.
  • Flexibility – Can weld a variety of metals including stainless steel, titanium, magnesium, aluminum and copper alloys.
  • Portability – Lightweight and portable, runs on engine powered generators or battery sources.

  • Safety – Non-flammable gases make it safer than other welding processes.

What are the Drawbacks of TIG Welding?

  • Slower Welding Speed – Typically slower than other welding processes due to the precision it requires.

  • More Complex – Can require more preparation and more experience than other welding processes.
  • High Setup Cost – Requires more expensive equipment, such as a welding machine.



TIG welding is a very precise and popular welding process, used to join various metals. It is known for producing high-quality welds with minimal post-weld clean-up, and the ability to weld a variety of metals. That said, it is slower than other welding processes, more complex to operate and its higher setup costs need to be considered.
