The welding industry as a whole incorporates several means and methodologies of completing welding projects. MIG welding, soldering and arc welding are just the start of an extensive list. Another way to fuse metal comes in the form of TIG welding, and young welders might wish to earn their TIG welding certification. To help you understand more and aid in your decision, let’s take a quick look at what this process is and its real world uses.

Introduction to TIG Welding

Tungsten Inert Gas (TIG) welding is a strategy that involves using a tungsten electrode to heat the metal that is being welded. To protect the weld from contamination during the process, shielding in the form of inert gas, like argon, is used and can be used for any metals/thicknesses. TIG welding is highly regarded because of its quality and applicability. Indeed, the process can be applied to more metals than any other method, capable of welding metals like steel, bronze, nickel, brass, copper, magnesium, aluminum and gold. Welding in a TIG operation is very precise and clean, allowing for a superior appearance. This is because a welder can increase and reduce the amount of heat that is used in the process, by means of a foot pedal, in order to better control the weld. In terms of cleanliness, TIG welding doesn’t result in sparks or create smoke and fumes.

TIG Welding Applications

Because TIG welding can be used with such a large variety of metals, the process can be applied to several industries and aid in the creation and repair of many items. This form of welding is common in the aerospace, automotive, repair and art fields. For instance, here are some types of TIG welding jobs:

  • Aerospace – Aircraft and spacecraft are constructed in part by means of TIG welding. So, the commercial planes used every day, as well as complex craft like the International Space Station have benefitted from such processes as TIG welding which is known for its strength and precision.
  • Automotive – Safe and secure construction is essential in the auto industry, as is making vehicles stand the test of time. For these reasons, TIG welding is widely used in the automotive industry. TIG strategies are known to reduce corrosion over time, so car fenders are frequently welded in this way to avoid rust. Besides this, the better the vehicle is constructed, the safer it will be for those travelling in it.
  • Repair – TIG may be used in a number of repair applications. From fixing a child’s toy, like a wagon or old-fashioned pedal car, to repairing aluminum tools, this welding method comes in handy.
  • Art – TIG is touted for the superior cosmetic appearance it results in. Artworks are about the artist’s message, yes, but they also rely on appearance. Therefore, works like industrial fixtures or metal sculptures may rely on TIG welding processes.


TIG welding is a highly flexible process given its ability to be the technique of choice for so many metals and its extreme precision. Individuals working in the welding industry certainly have their choice of focus areas—from automotive to repair and beyond. Think a career in welding is the right path?
