Gas Tungsten Arc Welder

The machine is used for Gas Tungsten Arc Welding (GTAW ), also known as TIG (Tungsten Inert Gas) welding. It is a commonly used high quality welding process.

Working Principle
TIG welders or GTAW machines use a permanent non-melting electrode made of tungsten. An arc is formed between the tungsten electrode and the metal being welded. Gas is passed through a torch to shield the electrode and the molten weld bath. Filler metal is added separately, that makes the process very flexible. Welding can also be done without filler material.TIG welders use alternating current (AC) source. Direct current or DC source can also be used, but in rare cases.

Shielding Gases Used

• Argon
• Argon & Hydrogen
• Argon & Helium

Advantage of GTA Welders
The various advantages of using TIG welders are:

• Welds can be made with or without fillers
• The process is spatter free
• Yields high quality welds
• Low distortion
• Accurate control of welding variables like heat

Uses & Applications
TIG welders are used for various purposes. Some of its popular application areas are:

• Manufacturing Industries
• Automotive Industry
• Pipeline Construction
• Power Plants
• Construction Industry
• Aerospace Applications
