Description
Esab Arc Machines Model 6 Tubesheet weld head
The Esab Arc Machines Model 6 Tube Sheet Weld Head 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
• Unlimited torch rotation
• Welds in any position, including overhead
• Can weld projected or recessed tubes with filler wire,
or flush joints without filler wire
• Makes multiple-pass welds without stopping
• Air-operated fixtures speed up production
• Servo-controlled AVC, rotation and synchronized wire feed
• Water-cooled torches
• Adjustable torch tilt
• Automatically sets distance between electrode and
tubesheet before arc initiation
• Non-linear vertical tungsten travel prevents tube-end burn-off
• Pulsed current welding and synchronized pulsed wire-feed
Esab Arc Machines Model 6 Torch options
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 burnthrough 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. Gas chamber for welding titanium available.
• “C” torch – for fillet welding of projected tubes
• “D” torch – for fillet welding of projected tubes with minimum
spacing between tubes
• “E” torch – for welding flush or recessed tubes
