Tungsten Inert Gas (TIG) welding also called as Gas Tungsten Arc Welding (GTAW) is a widely used welding process where there is requirement for high weld strength and clean weld. This process generates an arc between a non-consumable electrode (Tungsten) and the weld plate either through contact or by using high frequency (HF) power for fraction of time. This arc and the weld pool is shielded with inert gas (Argon). The filler wire/consumable is fed manually using a hand.
These industries require highly reliable weld quality which can be achieved only through TIG welding.
TIG welding process is widely used in assembly of exhaust systems, fuel tanks, body panels, and other structural components in the automotive industry.
TIG Welding is mainly adopted in manufacture of food and pharmaceutical equipment for clean and hygienic welds.
TIG welding is used in the fabrication industry to join non-ferrous metals like aluminium and copper. It’s also used in tool and die repairs.
TIG welding is used for pipeline and pipe welding, especially for industrial pipes.
TIG welding requires welders who are more qualified and skillful. Extreme stability of the hands and hand movement are key for beautiful weld joints.
TIG welding is high skill and time-consuming welding process.
UV radiation produced from the ARC generated in TIG welding can be more intense than sunlight. Even a short exposure can cause redness, which can worsen with increased intensity and exposure time. Overexposure to UV radiation can also cause skin burns and can increase the risk of skin cancers.
Latest advancement in welding technology addresses the above problems and thereby make TIG welding process more adaptable. One of these being the automation of feeding of the consumable in TIG.
Cold wire feeding facilitates automatic feeding of the consumable in TIG welding, thereby reducing the in-efficiencies (unstable and non-consistent feeding) of manual feeding of consumable.
