Application /
Properties:
Agglomerated alominate-basic
type flux for welding of
mild and medium steels.
AP380-3 produces a
slight silicon and
manganese pick-up.
Owing to its
metallurgical behavior,
it can be used with S2Mo
and S3Mo wire
electrodes.
It is suitable for
longitudinal welding
system. The flux has a
high current carrying
capacity and as such is
suitable for fillet and
butt welding
applications especially
for weld in heavy
section steels work. The
weld bead is of uniform
profile with
smooth weld bead profile
and good blending at the
weld toes even at high
welding speeds.
The slag detachment is
good and in most cases
is self-lifting.
AP380-3 can be used on
either. DC (positive) or
AC up to 1200 A on a
single wire.
Damp flux shall be
retried by baking at
300-350°C
Grain size in according
with DIN 32 522:3-18.
