Type/
Characteristics:
AMA OP 10 U is
an agglomerated
flux for use as
the backing
medium in the
single-sided
submerged arc
welding process.
For single-sided
welding the
backing flux is
spread as a thin
layer of a few
millimeters in
thickness in a
copper backing
bar which is
pressed against
the underside of
the weld joint.
After welding
the slag
detaches easily
and the root of
the weld
exhibits a
uniform profile.
AMA OP 10 U is
suitable for use
with single,
tandem and
multi-wire
submerged arc
welding
processes. The
optimized fine
grain size in
combination with
the flux
chemistry of AMA
OP 10 U ensures
that the weld
profile is
straight, with
clean weld toes
and a smooth
cosmetically
acceptable
surface.
Damp flux should
be redried by
baking at
300-350°C |
