Something about TIG from Pure Tungsten Electrode

Pure tungsten electrode is the first one kind of electrode used in TIG welding technology. TIG, whose English full name is Tungsten Inert Gas, often called non-MIG welding. TIG is a kind of gas shielded welding method, in which inert gas (argon) as a protective medium, and tungsten electrode in which is only playing a conductive role without melting, there will be arcing between them when it is energized, tungsten electrode and the workpiece. During the welding process, it can be filled with wire or without wire. If you need to fill in the wire, the wire should be filled from the front of tungsten.

TIG welding can be divided into: manual welding, automatic welding, in which manual welding of pure tungsten electrode is widely used, and in the aerospace industry, it has been used on welding high-quality work.
TIG welding technology has the following advantage: good welding quality; convenient operation of the arc and the pool (due to its good visibility); without little or no slag (because it does not using flux), and you do not need to clean up slag after welding.
Pure tungsten or activated tungsten - thorium tungsten, cerium tungsten, zirconium tungsten, lanthanum tungsten, as non-consumable electrode to shield arc, and it having high quality but its welding speed is relatively slow.
