If it’s thinner (1mm or 2mm), K-TIG welds in TIG (melt-in) mode. In this mode the weld will be single pass,
If it’s thicker than K-TIG's maximum penetration, outstanding productivity benefits are realised by combining a deep full-penetration K-TIG root pass, with a shallow v-prep which is filled using the K-TIG wire feeder. This equates to fewer passes, reduces fill and reduced welding times for any thickness. The filler pass can be performed by K-TIG or by another welding process.
The K-TIG system welds effortlessly in 1G and 2G welding positions. It’s not intended for orbital (5G/6G) applications.
Copper and aluminium cannot be welded with K-TIG.
To ensure your success we will review your material mill certificate and we’ll weld a coupon for you. Our goal is to allow you to leverage our expertise to ensure outstanding results for your company.
K-TIG can readily weld pipe diameters down to 4 inches NB (114mm OD). The tie-in on pipes with diameters smaller than 4 inches become challenging as the weld is completed within seconds and the tie-in (joining the beginning and end of the weld) must be performed over
We’re proud to say K-TIG has exported to 20 countries and has been adopted by some of the world's most advanced and productive fabricators.
In addition, we have seen dramatic productivity improvements in general industrial applications. Particularly in Process pipe fabrication, Pipe & Tube mills, Tank & Vessel fabrication across a wide range of industries.
We actively partner with leading advanced manufacturing

A K-TIG welding system is delivered as a fully integrated welding cell comprised of the K-TIG 1000 controller, torch, power supply, water cooler, wire feeder and torch mount with compensating slide.
The only additional requirement is some form of automation to provide consistent torch travel speed - this can be almost any kind of welding automation including rotators, positioners, turntables, seamers, carriages, robots, column and booms and many others. During commissioning, the K-TIG controller will be integrated with your automation equipment.
Customers with applications in K-TIG’s ideal thickness range and materials have reduced their welding costs by in excess of 90%.
Switching from GTAW to K-TIG
Relative to conventional TIG/GTAW welding, productivity gains and overall savings of more than 70% are typical, and savings in excess of 90% are common.
Switching from Plasma to K-TIG
Relative to Plasma Arc Welding (PAW), productivity gains of more than 50% are typical.
How are the savings achieved?
Incredibly fast welding times result in dramatic reductions in gas and power usage. Large single pass welds significantly reduce, or eliminate, grinding and reworking. Often edge bevelling is eliminated in favour of simple square butt preparations.
K-TIG can calculate your savings and productivity gains, offering:
On request, K-TIG will generate a K-TIG Savings Assessment at no cost for potential customers with applications which are within K-TIG’s normal thickness ranges
Customers with applications in corrosion resistant materials in an ideal thickness range generally save in excess of 90% relative to their current welding costs.

K-TIG is a GTAW variant, not a new welding process. K-TIG is code permissible in any application in which TIG/GTAW is allowable.
K-TIG is one of a large number of GTAW modes/variants as defined by ASME.
ASME doesn’t distinguish between GTAW and it’s variants (ASME under ASME QW-256 (Essential, Supplementary Essential and Non-Essential Variables for GTAW)). GTAW and its variants are all considered the same process under ASME.
Wire can be added to any K-TIG weld. The wire feed rate can be completely automated to suit your applications requirements and preferences.
K-TIG can also be used without the requirement of filler material. Autogenous welding can be qualified to rules of ASME Section IX, QW-256 for K-GTAW.
Procedure development for a K-TIG weld typically takes minutes or hours, not days or weeks. The Keyhole TIG process is simple and can be used in broad operating windows.
K-TIG welds are extremely consistent. Once the procedure has been established, it can be saved to the controller. That ensures high quality, repeatable welds that are fully compliant with an approved procedure.
The running costs of K-TIG welding systems are extremely low. K-TIG’s high speed welding significantly reduces arc-on costs, like gas and power, and system consumables are negligible.
If the travel speed is consistent, your existing welding automation equipment can generally be used (and integrated) with the K-TIG system.
During commissioning, the K-TIG controller can be integrated with your automation equipment. The K-TIG system can be integrated very simply, or extensively so the entire welding sequence is reduced to a push-button solution.
It is necessary to use the K-TIG power unit due to the high level of integration which is required between the controller and the power unit. It is not possible to connect the K-TIG controller to other power supplies.
K-TIG can provide a detailed ROI (Return on Investment) assessment for your specific application - we call these our Weld Savings Assessment. In general terms, the ROI on a K-TIG system can be as little as several months due to the dramatic cost reductions.
If you are a fabricator welding corrosion resistant materials, K-TIG will review your application and provide you with a Weld Savings Assessment, at no cost. These assessments are compiled individually by our team and will be emailed to you personally. Our team will be available to you for any follow-up questions you may have regarding your assessment.
