Keyhole TIG is a unique process developed in Australia that is gaining traction around the world. The advantageous material flow in keyhole welding ensures a high-quality weld and makes it possible to complete the weld in a single pass, providing huge productivity advantages. At a water pipeline infrastructure project in San Juan, Argentina, the total K-TIG arc-on time to fabricate 40ft (12m) long, 4ft (1.2m) diameter pipes made up of 7ft (2m) sections is approximately 2.5 hrs.
