4 Inactive
or “neutral” fluxes can be defined as those fluxes whose deposit strength
is not significantly altered by
the amount of flux fused, which varies with welding voltage. Similarly, “active”
fluxes (which should be restricted
to single or limited multi-pass welding) can be defined as those fluxes which
significantly increase weld
metal strength with increasing flux consumption occurring at higher voltage levels.
Using these descriptions,
ESAB 350, 282 and 231 fluxes can be considered “active” fluxes, and
ESAB 80, 124, 709-5, 656,
and 429 can be considered “neutral” fluxes. ACTIVE
(“NEUTRAL”)
INACTIVE Gains
of Mn & Si are dependent
on the amount
of flux fused or
voltage used. Gains
or losses of Mn and
Si are not significantly
affected by amount
of flux fused or voltage
used. CAUTION:
All materials selection recommendations
are based on an evaluation of mechanical properties,
typical procedure parameters and experience. It is the user’s
responsibility to determine the suitability
of the materials for his application, considering
the particular procedures to be used and the requirements of the
specific job.
