Tungsten Inert Gas (TIG) welding, also known as Gas Tungsten Arc Welding (GTAW) is an arc welding process that produces the weld with a non-consumable tungsten electrode. Tungsten inert gas (TIG) welding became an overnight success in the 1940s for joining magnesium and aluminium. Using an...
Inert gas is used in MIG welding (metal-arc inert gas welding) while active gas is used in MAG welding (metal-arc active gas welding). An example of inert gas is argon, which does not react with the molten weld. It is the most commonly used shielding gas in TIG welding. Carbon ...
Tungsten Inert Gas Welding TIG welding is a process that enables top-quality weld seams. The arc burns between a temperature-resistant, non-melting tungsten electrode, and the workpiece. The inert shielding gas that gives the process its name creates an oxygen-free gas atmosphere and prevents che...
The TIG welding process, from the group of gas shielded arc welding, offers optimum quality and visually pleasing, spatter-free weld seams.
2) Gas Tungsten Arc Welding (GTAW) GTAW, or TIG welding, uses a non-consumable tungsten electrode to produce the weld. A separate filler metal is used to join the pipes, and an inert gas like argon protects the weld area from contamination. ...
Friction welding doesn't require the use of filler metals, flux or shielding gas. Friction is frequently used in aerospace applications as it is ideal for joining otherwise 'non-weldable' light-weight aluminium alloys. Friction processes are used across industry and are also being explored as a...
TIG-HW is a further development of conventional TIG (Tungsten Inert Gas) welding. In this process, an additional wire is electrically preheated before it is introduced into the melting area. This leads to a significant improvement in the deposition rate and efficiency of the welding process, min...
Accompanying the weld head during orbital GTAW is the gas supply nozzle which provides a constant supply of shielding gas to the weld head to create a high-purity weld. In most cases, the welding head also comes with cooling lines (air or water-cooled) to prevent overheating and dam...
MIG/MAG welding is also referred to as gas metal arc welding. MIG/MAG welding systems ignite the arc using a filler metal.
Inert Gases are often used in situations where reactivity is undesirable. To prevent oxidation, Inert Gases are used in welding processes. 10 Noble Gases Noble Gases rarely form compounds due to their full electron configurations. Krypton, a Noble Gas, is sometimes used in high-performance window...
