Automated orbital welding carriage
THE Gullco Pipe KAT® is an automated
orbital welding carriage designed for
pipe welding applications. Suitable for
field pipeline manufacturing and power
plant construction, the Pipe
KAT is a fully integrated
welding system that includes
a remote control pendant to
allow adjustment of critical
application parameters
during the welding process,
including oscillation width,
speed, dwells, wire feed speed and
voltage adjustment.
The carriage operates on a track band
made of durable aluminium extrusion
by engaging the track with self-aligning
wheels and a rack and pinion drive. This
wheel assembly uses a lever to engage
the track, making it quick and simple to
install the carriage.

Tool line takes bite out of tube end finishing
FOR manufacturers of tubing products,
or those who manufacture products with
tubing components, Severance Tool has
developed a line of tube end-finishing
rotary tools that can de-burr, form or
chamfer as required by application
needs.
The tools are designed to finish both
the inside diameter and outside diameter
of tubing ends in a single operation,
and many feature adjustable two-piece
construction to accommodate work on
same-size tubing having varying wall
thickness ranges.
Depending upon the application, other
features may include Chatterless™
tooth geometry, which alternates tooth
cutting angles to eliminate resonant
vibration from the tool and workpiece
for smooth finishes, and Severance’s
exclusive Grayhone™ finish, which
provides cutting edges ready to work
with no break-in period required.
Among the tools offered are a full line
of tube de-burring tools available in high
speed steel or carbide construction.
Although they provide a 30° inside
chamfer and a 45° outside chamfer,
these tools are designed for light duty –
to break sharp edges of both the inside
and outside diameter simultaneously.
They feature tooth geometry with a
shearing cutting action for fast cutting
that prevents loading of chips.
The tools can be reground numerous
times for long service, and operate in
speed ranges of 50 to 200rpm. The
outside ring or member is adjustable,
secured by screws, to provide various
outside edge break sizes and to
compensate for different wall thicknesses
within a given tube diameter range.
Tube de-burring cutters are available in
standard sizes for 1/ 8" outside diameter
(1/16" inside diameter) to 21/4" outside
diameter (2" inside diameter) tubing, and
with a variety of shank
styles.
Tube end chamfering
mills provide the same
shear cutting action
and adjustable outside
ring as the de-burring
cutters, and with
Chatterless™ angle
geometry are designed
for heavy duty cutting
to machine precise,
smooth 45° outside
diameter and 30° inside
diameter chamfers in
applications requiring
easy assembly with
other components.
Chamfering mills are available in
sizes for pipe and tubing ranging from
3/16" to 21/2" outside diameters.
The tube end-forming cutters
machine both an inside diameter and
outside diameter radius, establishing
a smooth, rounded end that is suitable
for applications where tubing may be
exposed. A selection of high speed
steel and carbide tools are available
in sizes for tubing ranging from 1/8" to
2 1/2" outside diameters; each outside
diameter size is complemented by a
range of wall thickness or gauge sizes
to accommodate most popular tubing
applications.
Severance also provides an
application-specific design and
manufacture service, including custom
sizes, chamfer angles and forming
characteristics. Single cutting action
(inside diameter or outside diameter)
chamfering tools are also available, and
the company offers a wide range of tool
styles and sizes for de-burring holes
through tube walls.
Other Severance tools include 3N1 ®
combination countersink/drills, Midget
Mills® rotary files and burrs, inside and
outside de-burring and chamfering mills,
Micro-Reamers™, electrode dressers,
double-end countersinks, Chatterless™
countersinks and adjustable stop
countersink units, stop countersink
cutters, and a variety of hand-operated
finishing tools.
