UNGT High Speed Oscillating Ultra Narrow Groove Torch

The NEW High Speed Oscillating Ultra Narrow Groove Welding technology is a significant advancement in narrow groove welding, and it builds on the mechanical oscillating narrow groove technology that was pioneered by AMI in the early 90’s. This new High Speed Oscillating technology allows users to weld in narrower grooves than ever before while achieving quality side wall fusion when welding and repairing heavy-walled components.

 

Among the many advantages of High Speed Oscillating Ultra Narrow Groove welding are:

► Higher productivity rates
► Reduced weld volume (80%+ vs. conventional grooves)
► Lower heat input

While traditional weld preps are 37.5 degree wide, High Speed Oscillating Ultra Narrow Groove welding uses a 0.31”to 36” (8 to 9 mm) wide groove with 2 to 5 degree sidewalls which requires much less filler metal and results in higher quality welds due to efficient heat input and shorter weld times.

UNGT benefits:

  • Reduced weld volume   shorter welding time.
  • Lower heat input  less residual stresses.
  • Less consumption of filling material and shielding gas.
  • Improved weldment properties.
  • Lower incidence of weld metal defects.
