Application /
Properties:
Agglomerated alominate-basic
type flux for welding of
mild and medium steels.
AP124 produces a
slight silicon and
manganese pick-up.
Weld metal toughness ,
low temperature is good.
The weld bead is of
uniform profile
with smooth weld bead
profile.
AP124 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.
