Tube to Tubesheet Welding Systems - Arc Machines, Inc.
The Model 6 is a rugged, field-proven weld head for high-production welding of tube-to-tubesheet using the GTAW process. The Model 6 has exceptionally fast mount and dismount times for ease of operation and productivity. The torch is positioned on the tube to be welded by a pneumatically operated locating fixture. With the touch of a button, the locating fixture precisely locates itself over the tube to be welded.
Rugged, reliable tube-to-tubesheet weld head with 200 A torch
Welds projected or recessed tubes with filler wire, or flush joints without filler wire.
Unlimited torch rotation
Makes multiple-pass welds without stopping
Self-supporting on tubesheet
Air-operated fixtures speed up production
Welds in any position, including overhead
The “C” and “D” torches (for fillet welds)
are spring-loaded torches with a chill follower. The chill follower is
located on the inside of the tube to be welded and contacts the tube
wall exactly opposite the electrode, thus minimizing the possibility of
burn-through on thin-wall tubes. The mechanics of the spring-loaded
torch allows it to perfectly track the shape of the tube regardless of
minor ovality. The "E" torch is for welding flush or recessed tubes.
Compatible with the AMI Model 227 and Model 415 Power Supplies.
