MIG/MAG GAS NOZZLES
ABIMIG® AIR COOLED SERIES
Screw-on
It is one of the most important equipment parts of a
MIG/MAG welding torch: the gas nozzle, often also
called shroud. The task of the gas nozzle is to allow
the shielding gas required for the welding process to
flow into the process evenly and laminar, so that a
constant shielding gas coverage of the arc and the
weld pool against the atmosphere is guaranteed.
Screw-on gas nozzles are more firmly attached to
the torch head in comparison. They also guarantee a
centric alignment of the nozzle and are ideally suited
for use on welding robots, where they maintain their
centring even during mechanical cleaning. Many of
the screw-on gas nozzles are preferred for robotic
welding.
There are elementary differences in terms of material
selection, processing and quality. With gas nozzles
from ABICOR BINZEL, you have a wear part that
meets the existing requirements in the usual premium
quality.
Material & Properties
Special Nozzles
The basic material of a MIG/MAG gas nozzle is
usually copper alloy, sometimes pure copper is used.
Others have an additional coating of nickel, for example, to prevent adhesion or the burning in of weld
spatter from the MIG/MAG process and thus ensure
a longer service life of the shroud. In addition, the
advantage of these coatings is that weld spatter is
easier to remove again because it does not burn in
as deeply.
Some welding tasks require special solutions for
accessibility and heat dissipation. Angles that are
difficult to reach, deep gaps in thick sheets or even
extreme heat in the process are conditions that can
be improved resp. the work made easier with suitable
wear parts.
Special gas nozzles:
Bottle Style
Nickel-plated
ABIMIG® welding torches from ABICOR BINZEL have
highly polished nickel-plated gas nozzles, which therefore
reflect the heat best and thus protect the shroud and the
welding torch as a whole very well against spatter adhesion. Compared to conventional gas nozzles from the MB
range, these even have a longer service life.
As the name suggests, the front end of this gas nozzle is
tapered like the shape of a bottle. Bottle-shaped gas nozzles allow both good accessibility and a good view of the
workpiece and the weld seam. The gas cover is narrower
than with conical gas nozzles.
Narrow-gap
The narrow-gap gas nozzle is used where even with bottle-shaped ones you can’t get by. It is a specially shaped
gas nozzle for example for narrow-gap welding and single-sided through-welding of HP profiles in shipbuilding.
Plates up to a thickness of 50 mm can be welded with narrow-gap gas nozzles.
