AMI Model 96 Series Weld Head

Description

The AMI Model 96 Series Weld Head is a compact, automated weld head
designed for high-speed, high-production autogenous
welding of tubes to tubesheet. Welds made with the
Model 96, utilizing the GTAW (TIG) welding process,
can pass the most rigid specifications.
The weld head is held in place on the tube to be welded
by an expanding mandrel. This mandrel is actuated by
a single button, conveniently located on the handle.
Actuation of the mandrel holds the weld head firmly to
the tubesheet and positions the torch concentric to the
tube to be welded. The Model 96 features a completely
enclosed purge chamber. The gas chamber eliminates
the use of gas cups and provides superior shielding for
materials which oxidize easily, such as titanium.

Features:

• Welds on flush, slightly recessed or slightly projected
without the use of filler wire
• Pulsed-current welding, and synchronized torch rotation
• Servo-controlled rotation
• Pneumatic mandrel operation
• Transparent or opaque purge chamber
• Self-supporting on tubesheet
• Complete coverage of weld area with inert gas
• Welds in any position, including overhead
• One-button operation, quick mount and dismount
• Water-cooled weld head
