TIG welding is an arc welding process in which weld is produced making use of a non-consumable tungsten electrode. TIG (tungsten inert gas) welding generates an electric arc between the tungsten electrode and the workpiece, and join metals using the heat generated. An inert shielding is usually used to protect the weld area against atmospheric contamination. In order to carry out TIG Welding, welding experts would require TIG welding machine, tungsten electrode, shielding gas supply, filler metal rod and personal safety equipment. TIG welding done to join metals with superior weld quality can be used with or without filler metal, based on the application requirement.
