What Are the Best TIG Welding Tips?

TIG welding is tungsten inert gas welding, which is generally called non-melting electrode gas shielded welding.

TIG welding

Inert gas shielded arc welding using pure tungsten or activated tungsten (rhenium tungsten, cerium tungsten, zirconium tungsten, lanthanum tungsten) as the non-melting electrode, and using the arc between the tungsten electrode and the workpiece as a heat source to melt the added welding wire to form a weld seam of. The tungsten electrode does not melt during the welding process and only serves as an electrode. At the same time, argon or helium is sent from the nozzle of the welding torch for protection. Additional metals can be added as needed. (Internationally known as TIG welding. Tungsten Inert Gas, abbreviated TIG.)

TIG welding advantages

The main advantage of TIG welding is the wide range of materials that can be welded. Including workpieces with a thickness of 0.2mm and above, the materials include alloy steel, aluminum, magnesium, copper and its alloys, gray cast iron, ordinary steel, various bronzes, Nickel, silver, titanium and lead. The main field of application is welding thin and medium thickness workpieces, which are used as root welding beads on thicker sections.

Disadvantages of TIG welding

The TIG welding method has strict requirements on environmental wind. When the ambient wind is greater than 4m / s, it will affect the gas protection effect, and the welding efficiency is low, which is suitable for welding some fine product components;

Low welding efficiency and high cost;

Strict requirements for cleaning before welding;

Special arc ignition measures are needed, high frequency arc ignition is harmful to human body;

Strong ultraviolet rays and high ozone concentration.
