Q:

What type of materials is TIG welding suitable for?

A:

Quick Answer

TIG, or tungsten inert gas welding, is suitable for materials such as aluminum, magnesium, stainless steel, titanium and carbon steel. A versatile welding method, TIG welds nonferrous metals, nickel alloys, copper and gold. TIG welding is comparatively slower than other welding methods, but it produces precise, high-quality and durable welds. This welding method works well for thin nonferrous metals as well as for joining dissimilar metals.

TIG welding finds application in many diverse areas, including the aerospace, automobile, nuclear and chemical industries. This form of welding involves using a non-consumable tungsten electrode along with an inert gas such as argon or helium. The inert gas helps protect the electrode and weld pool from atmospheric contamination. The process maintains a constant arc between the tip of the electrode and the welding material. A filler metal may be applied separately depending on the material and application.

TIG welding produces superior and stronger welds than other methods, and users of TIG welding produce joints such as butt joints, T-joints, lap joints, fillet welds and corner joints. This form of welding produces no slag or splatter with little smoke or fumes, and the concentrated arc allows for better heat input and control. However, TIG welding has a slower deposition rate and requires greater expertise to operate.
