Magnatech, USA, has introduced a new
completely digital GMAW/FCAW orbital pipe
welder, based on the successful Pipeliner
brand. The new model was developed with
the knowledge gained during many years of
field experience with the original Pipeliner ll.
The Pipeliner II system, using the forgiving
flux core arc welding process (FCAW),
has gained wide acceptance by pipeline
contractors. Unlike systems on the market
using the solid wire gas metal arc welding
(GMAW) process, the Pipeliner ll has
repeatedly demonstrated that it can meet
both API 1104 and ASME code standards.
Contractors throughout Europe, as well
as Saudi Arabia, Qatar, Oman, Thailand,
and the United Arab Emirates, have used
the system for critical gas, oil
and water pipeline projects
requiring higher strength
steels, such as X-70, X-80
and above.
Previous models used a floor-
mounted push-only feeder, or
mounted a smaller wire feeder
and spool directly on the weld
head. The new model utilizes
a push-pull feeder for positive
electrode delivery, while
allowing use of standard 15kg
wire spools.
The FCAW process allows heavier wall pipe
to be welded (not possible with mechanized

a special narrow gap joint geometry. The
weld head is adaptable to pipes for 6-60".
The digital model allows programming by
position (degrees of rotation). A hand-held
control pendant allows the operator to make
changes in all parameters during welding
to meet field fit-up conditions. Supervising
managers can also password limit changes
to each function and also limit the total
magnitude of any change. For example, a
change in weave width would be allowed,
but only to a maximum of ±10 per cent of
the programmed value.
The new system is sealed to IP23 rating
for waterproof and dust proof operation
on the pipeline right-of-way. This system
is equally suitable for use on pressure
and process piping as well as structural
projects. The Pipeliner FCAW process
is 12-18 times faster than stick electrode
welding.

Slitting saws and circular knives
Caleyron Industries manufactures
solid carbide and HSS slitting saws
and circular knives from 20mm to
300mm diameter. These up-market
tools can be used to cut hard
materials.
Clean cut surfaces and close
tolerances are obtained due to a
mirror finish and a perfect geometry
of the saws. These blades allow
higher cutting speed and feed
rates as well high output. The tool
life of these saws is significantly
increased.
