MAGNETIC ARC OSCILLATING

NARROW GROOVE WELDING (GTAW)

The Advanced Choice for Automated Heavy Wall, Pipe,

Vessel, and Valve Welding

The NEW Magnetic Arc Oscillating 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 Magnetic 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 Magnetic Arc Oscillating

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, Magnetic

Arc Oscillating Narrow Groove welding uses a 0.31 "to 36" (8 to

9 mm) wide groove with 2 to 5 degree sidewalls which re-

quires much less filler metal and results in higher quality welds

due to efficient heat input and shorter weld times.

AMI Magnetic Arc Oscillating Narrow Gap Torch (NGT-MAG)

The Arc Machines NGT-MAG torch (Magnetic Arc Oscillating) is The Ultimate Solution for high

quality heavy-wall pipe and vessel welding.

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.

Since its launch in 1994, AMI has supplied

over 300 NGT Systems worldwide.
