Cut-off blades
KENT Corporation, in cooperation with a
tube-producing customer, has developed
a special cut-off blade for use in the most
difficult applications.
The new blade resulted in an increase in
life of over 200% over the standard blade.
Kent Corporation, the tube producer, and
the blade manufacturer achieved the results
through a vigorous testing programme. This
technical approach to increasing blade life
is available free to all blade customers
to make sure the blade they are using is
optimised for their application.
A new coating SNB is available as well
and has shown double to 10 times the life
on applications where excessive heat is
created.

Fresh era in
MIG/MAG welding
EWM’s alpha Q system provides six full-
scale welding processes in one machine:
coldArc® and forceArc®, MIG/MAG pulse
and standard processes, TIG (liftArc)
and MMA welding. It is possible to switch
between applications at any time, as well
as to combine different processes, while
retaining seam quality and efficiency.
The system allows the thinnest of panels
to be joined at low heat, in addition to
welding and brazing new materials and
mixed connections. EWM states that the
system’s excellent gap bridging allows root
passes to be handled easily and safely,
and that deep fusion penetration, simple
handling and a high welding speed mean
the high pressure, forced welding arc can
be used to weld thick panels while claiming
saved production costs of up to 50%.
This is provided by a single machine
combining the EWM coldArc and forceArc
processes, rounded off by a pulse welding
arc. These welding processes allow all
seam types to be realised from one power
source, and result in a welding seam with
such low spatter that post weld work is
virtually unnecessary.
The alpha Q range – 330, 351 and 551
– provides a system that can be flexibly
configured for specific applications, from
portable, modular or compact to mobile. For
alternating between coldArc and forceArc
welding, a twin case or two individual wire
feed units are available, so the user always
has the required filler wire and gas.
