What is TIG Welding Used for?

Metal Fabrication, Welding | July 29, 2021

When it comes to metal fabrication, many types of welding can be used to join pieces of metal together. Understanding the differences between each type of welding is crucial for choosing the right approach for the project and the materials. As leading providers of quality metal fabrication and welding services, the team at LWS Manufacturing and Welding understands the importance of using the right techniques for the best results. That is why our team has provided some information on what TIG welding is used for and how it works to help you determine if it is the right option for your needs.

Learn about the differences between TIG welding and MIG welding.

How Does TIG Welding Work?

TIG (Tungsten Inert Gas) welding makes use of a non-consumable tungsten electrode instead of a metal electrode. Tungsten has an exceptionally high melting temperature, so TIG welding requires additional filler to be applied for each join. The operator feeds this filler into the weld area while operating the torch with another. During operation, the operator will simultaneously use one foot to operate a control pedal that determines the heat input. TIG welding is commonly used for jobs that require a thin weld seam and a clean finish, such as joining tubes together for food-grade applications.

Benefits of TIG Welding

TIG welding can be used for assembly production lines, on-site repairs, and other field applications. The main advantage of the TIG process is the exceptional final quality of the weld, but other benefits include:

  • The process can be used with or without filler wire in certain applications.
  • Highly versatile and can be used to join a variety of small or thin materials.
  • Minimal welding smoke or residue.
  • Most metals —stainless steel, titanium, magnesium, aluminum, and copper— can be welded with TIG.
  • Exceptional stability and can be applied in a variety of positions. In some cases, TIG welding can even be automated.
  • Defects are extremely rare when performing TIG welding correctly, resulting in a high-quality finish.

Potential Downsides

Though TIG welding produces high-quality results and can be used on a variety of materials, it is not without some drawbacks. Potential downsides of TIG welding include:

  • TIG welding equipment tends to require a higher cost investment than other equipment.
  • The process can take longer, making it unsuitable for time-sensitive projects.
  • Often requires a skilled and well-trained operator to ensure that the job is performed correctly.
  • Consumes more energy, slightly increasing utility costs.
  • TIG welding tends to require an entirely clean surface and work environment.
