All About The TIG

Just like kids who need to learn the alphabet, those who want to learn about TIG welding should be taught about the concept bit by bit. First off, we’ll start with what this welding process is.

What is TIG welding?

Tungsten Inert Gas (TIG) welding uses a non-consumable tungsten electrode (wire) to supply an electric arc for welding. There is a covering of inert gas that surrounds the electrode, the arc, as well as the area that will be welded. Compared to MIG welding, the electrode in this process isn’t consumed in the weld. There is also no metal added.

TIG welders can weld titanium, copper, and even two different metals together. TIG welding is best for complicated welds like curves and welds on round stuff. It also produces heat through an arc of electricity from an electrode to the surface of the metal. If you’re a beginner welder, it’s best to first master metal inert gas (MIG) welding before TIG because the latter requires more experience.

Welders use TIG welding to thin gauge materials, which is why they’re ideal for welding kitchen sinks and tool boxes.

TIG welders have the advantage of lowering their power down to avoid blowing through the metal. Note that MIG welders can’t do this.

Because of its controllability, TIG welding can also weld pipes, pressure vessels in shipyards and nuclear power plants, and other heavier materials. They just have to own a unit that’s capable of releasing the amount of power the welding machine needs.

What metals can TIG welding weld?

The process can be applied to a plethora of metals. Usually, TIG welding is used to weld aluminum and steel. Welding steel is straightforward and easy, and when you TIG weld steel, it produces incredibly tight and neat welds. On the other hand, welding aluminum requires more practice. But don’t be discouraged; the technique is basically the same, and most welders can switch from welding steel to aluminum relatively quickly.

As a versatile welding procedure, TIG welding can even weld exotic metals without any problem. In fact, no other process can weld unfamiliar metals as excellent as TIG welding.

Here are some of the metals that welders can TIG weld:

  • TIG-Welding-Sparks-and-Flame_Ultraviolet-LightAluminum
  • Copper Nickel
  • Hastelloy
  • Inconel
  • Magnesium
  • Mild Steel
  • Nickel
  • Stainless Steel
  • Titanium

The TIG welding process can also weld dissimilar metals together and can weld a lot of alloys and metals than the list above.
