TIG Welding

TIG Welding Points : TIG Welding process It is more usually referred to as TIG (tungsten- inert- gas) welding. TIG welding is a shielded- arc welding method that represent a special with more complex type of standard metal arc welding. The needed heat for welding is providing through a very strong electric arc, which is struck among a iron consumable tungsten electrode with the metal surface of work piece. TIG welding be different as of gas metal are (MIG) welding in that the electrode is not meted and is not use as a filler melted. On point where filler metal is necessary a welding rod is fed in to the weld joint and melted by the bottom metal in the similar way use by oxyacetylene welding.

TIG welding method uses tungsten electrodes to perform the electrical current to arc. They are and the molten puddle under the arc stream are shielded as of oxygen and other contaminants in the surrounding atmosphere by an inert gas (Helium or Argon) as gas is inert, it will not contact by additional elements to type other compounds and therefore give an efficient shielding for arc.
