    GTAW (Gas Tungsten Arc Welding) is an electric arc welding process using non-melted electrodes. In this GTAW welding, the electrode or tungsten is only functioning as an arc producer when it comes to contact with the workpiece, while the filler material is the filler rod.


  • What is GTAW (Gas Tungsten Arc Welding)? | Welding School

    GTAW, also known as tungsten inert gas (TIG) welding, is a type of arc welding which produces the weld using a non-consumable tungsten electrode. Inert gases such as argon or helium are used to protect the area being welded from contamination and most, although not all, welding applications will require filler metal.


  • Gas Tungsten Arc Welding - an overview | ScienceDirect Topics

    Peter Smith, in The Fundamentals of Piping Design, 2007. Gas Tungsten Arc Welding. Gas tungsten arc welding, also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a nonconsumable tungsten electrode to produce the weld. The filler metal is added from an external source, usually as bare metal filler rod. The weld pool area is protected from the atmosphere and ...


  • Gas Tungsten Arc Welding (GTAW / -TIG-)

    The gas tungsten arc welding (GTAW) process is a very versatile, all-position welding process that is widely used to join Ni-/Co-base alloys. In GTAW, the heat for welding is generated from an electric arc established between a non-consumable tungsten electrode and the workpiece.


  • Insider's Guide to Gas Tungsten Arc Welding (GTAW) / TIG ...

    Before the invention of Gas Tungsten Arc Welding (GTAW), difficulties were faced for welding nonferrous metals like aluminum and magnesium since their reaction with the air was very rapid, resulting in porous weldments. The present-day GTAW process was initially developed in 1941 using tungsten electrodes and helium as an inert gas.

    Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a non-consumable tungsten electrode to produce the weld.The weld area and electrode are protected from oxidation or other atmospheric contamination by an inert shielding gas …


  • TIG Welding or Gas Tungsten Arc Welding (GTAW)

    Gas Tungsten Arc Welding (GTAW) is also known as Tungsten Inert Gas Welding (TIG Welding). It is an arc welding process that uses a non-consumable electrode made up of Tungsten (or an alloy of tungsten).. In TIG welding, the arc is generated between the tungsten electrode and the workpiece to produce the necessary heat required for the welding. Shielding gas is …

    TIG stands for tungsten inert gas and GTAW stands for gas tungsten arc welding. GTAW was the official name at one time but it is now commonly referred to as TIG. An even less common name for GTAW is argon welding. In this type of process, shielding gas is used for welding. TIG/GTAW uses tungsten electrodes in the welding process.


  • Guidelines for tungsten electrodes - The Fabricator

    Choosing one of the six commonly available tungsten electrodes is a crucial first step in successful gas tungsten arc welding (GTAW). In addition, tip preparation is critical. The electrode choices are pure tungsten, 2 percent thoriated, 2 percent ceriated, 1.5 percent lanthanated, zirconiated, and rare earth. The end preparations are balled, pointed, and truncated.

  • Tungsten - Wikipedia

    Tungsten, or wolfram, is a chemical element with the symbol W and atomic number 74. Tungsten is a rare metal found naturally on Earth almost exclusively as compounds with other elements. It was identified as a new element in 1781 and first isolated as a metal in 1783. Its important ores include scheelite and wolframite, the latter lending the element its alternate name.
