Application /
Properties:
Agglomerated
aluminate-rutile
type flux for
welding of low
alloy steels
with Y.S<450N/mm2,
pipe steels
according to DIN
17172 and API 5L
steels up to
X70. Weld metal
hardness is less
than 240HV and
resistant to
sour gas
environment. AMA
OP 132 produces
a slight silicon
and manganese
pick-up. Weld
metal toughness
in low
temperature is
very good. When
this flux with
S2MoTiB or
S3MoTiB wire,
The toughness of
weld metal will
be increased.
using It is
suitable for
longitudinal
welding of sour
gas and oil
pipes and spiral
pipes at high
speed welding
with single and
multi-wire (up
to 5 wires)
welding system.
The weld bead is
of uniform
profile, good
wetting without
undercut. The
slag
detachment is
excellent.
AMA OP 132
can be used on
either DC
(positive) or AC
up to 1300A on a
single wire.
Damp flux shall
be redried by
baking at
300-350C
Grain size in
according with
DIN 32 522:3-18.
