What is K-TIG?

K-TIG is a single-pass, full-penetration keyhole welding technology which performs a 6 hour TIG weld in under 3 minutes - just 1% of the time normally required. The average cost saving of K-TIG customers is between 80 and 95 percent.

K-TIG is a GTAW process which requires no edge bevelling, uses as little as 10% of the gas normally required and produces highly repeatable, x-ray quality welds with superb cap and root aesthetics.

K-TIG welds meet US, European & Australasian welding standards including ASME IX, and have been subjected to exhaustive Lloyds-witnessed and certified testing.

K-TIG has been exported to 18 countries and is being used in production by many of the world’s most productive fabricators in numerous industries from pressure vessels and tanks to power generation and nuclear applications.




What are the benefits?

Dramatic productivity gains. Dramatic cost reductions. K-TIG routinely delivers savings in excess of 90%. Yes, you read that correctly.

K-TIG has 8x the penetration of GTAW, allowing it to perform x-ray quality welds in materials up to 5/8 inch (16mm) thick in a single pass, without the need for edge beveling.

The resulting welds are performed at up to 100x the speed of conventional TIG/GTAW.

K-TIG full penetration welding greatly reduces welding times, labour costs, filler wire consumption, repair costs, gas & power consumption and eliminates bevelling, grinding, back-gouging & reworking.

K-TIG’s deep penetration can be used to achieve single-pass welds on square butt joints or can be utilised with all standard GTAW preparations. K-TIG is suitable for both longitudinal and circumferential welding in 1G and 2G positions.

K-TIG welding is a new productivity benchmark. It sets an entirely new bar for what can be achieved with an arc welding system. The speed, penetration, quality and overall savings generated by the process are extraordinary.

How K-TIG works

K-TIG combines the high quality and cleanliness of GTAW with a depth of penetration that is unmatched by conventional gas-tungsten arc, gas metal arc or plasma welding processes.

The K-TIG keyhole which is opened through the joint is inherently stable, and operates over a very wide range of welding currents. Setup times are nominal and operation is extremely straightforward.

How does K-TIG compare?

K-TIG is a high performance, full penetration variant of the TIG/GTAW process which delivers productivity previously only possible with expensive laser, hybrid laser and electron beam processes.

Unlike plasma arc welding, there is only one welding gas and no orifice, making the process exceptionally robust and welding procedures highly repeatable in a wide range of materials, thicknesses and applications.
