Application / Properties:
Agglomerated
Manganese-Silicate type
flux for
welding general
structural steels,
pressure vessel steels,
pipe steels as well as
fine grain structural
steels. It produces a
mean silicon pick-up and
when used with wire
electrodes,
50-14,50-15,50-11,50-12 also a manganese
pick-up. The neutral
point for manganese is
at approximately 2% AMA
OP 119 can therefore be
combined with wire
electrodes having a low
manganese content.
It is particularly for
twin-wire, tandem and
multi-wire at high
speeds. AMA OP 119 is
likewise suited for
welding from both sides
in one pass,. For
increased weld metal
toughness, wire
electrode containing
molybdenum 50-14 should
be preferably used.
AMA OP 119 can be used
on either DC or AC up to
1000A (in single wire
welding),
Slag removal is easy.
The resulting slag is
short, i.e.g., girth
seams on work pieces
having a small diameter
can be welded without
the danger of the slag
running off.
Damp flux shall be
retried by baking at
300-350C

with DIN 32 522:2-20.

For welding from both
side in one pass,
especially in multi-wire
welding
50-14 wire electrode
should be used
because of the
fine-grain formation
caused by molybdenum.
