How does K-TIG compare to TIG welding?
Conventional TIG/GTAW is a melt-in process. Surface tension causes the molten metal to circulate, moving the heat first to the sides and then flowing to the bottom of the weld pool, before returning to
K-TIG, on the other hand, maximises the arc pressure to create enough force to penetrate the materials being welded. K-TIG uses higher than conventional welding currents, usually between 320 and 600 amps and even higher if a thicker material needs to be welded.
After the material has been penetrated, the K-TIG process creates and maintains an incredibly stable ‘keyhole’. The cavity can convert to a self-stabilising structure by using the sides of the pool as an elastic membrane, attached to the top and bottom opening in the material.
The self-stabilising nature of the keyhole makes the entire process highly efficient by only melting the amount of material required to achieve full penetration. In comparison to conventional
Both TIG/GTAW and K-TIG only use one gas throughout the welding process, typically argon although mixes can be used to optimise particular applications. Gas is delivered in K-TIG in the same manner as conventional TIG, flowing down the electrode and the gas cup.
The Benefits of Switching
How does K-TIG overcome the issues of TIG Welding?
K-TIG overcomes the most common issues associated with TIG:
I’m currently using TIG, can I switch to K-TIG
Absolutely! If you have some simple automation equipment or are willing to invest in it, weld with materials thicker than 3mm and larger than
How Do I Change to K-TIG?
It really couldn’t be easier.
If you’re currently using TIG, the upgrade process is simple. Your existing welding automation system can still be used.
