Nearly all
Magna oxyacetylene welding,
brazing and soldering alloys require the
use of a companion Magna Welding
Flux.
Each
Magna Flux is calibrated to provide
optimum performance with the Magna
Welding Alloy it was designed to be used
with. The numbering system used makes it
easy to know which Magna Flux to
use with a specific Magna Alloy. All the Alloys in the Magna
maintenance range that require a flux
are of two digits (all Magna
maintenance welding electrodes are 3
digits). The Flux is packaged in
unbreakable plastic jars and has the
same number as the welding alloy it was
formulated to be used with. Thus, with
Magna 65, as an example, the
welder readily knows to use
Magna 65 Flux.
Some of
the Magna Maintenance Alloys for
torch application have the flux coated
on the filler rod. In this case the
letter
'F'
is added to the two
digits. Examples are
Magna 33F
and Magna
75F. However, extra flux is
available in standard non-breakable
plastic jars because on some
applications extra flux is required. For
example, when flowing an alloy through
an exceptionally long lap joint, or when
welding exceptionally dirty metal, extra
flux is helpful.
Magna Fluxes
are quite different from ordinary
production type Fluxes. The purpose they
serve is immensely important to the job
at hand and they are not related to the
ordinary borax, water and dye that make
up a large percentage of what is
currently being sold as - flux. They are
the result of many years of scientific
research.
Here are four good
reasons for using Magna Fluxes:
(1)
Magna Maintenance Engineered Fluxes
have built-in
'Super
Energy'. Every
liquid (and molten weld-metal is no
exception) has a force known as
surface-tension. Surface tension is the
result of the liquid making an effort to
minimize its surface and to satisfy the
requirements of the lowest state of
energy.
Molten metal has a
tendency to draw itself into the shape
of a sphere, globule or droplet, and
this shape (in welding terms) has the
smallest surface of any geometric
configuration - with an equal volume.
Substantial energy is
required to change the geometric
dimensions of the weld deposit.
Especially so since it must be done
instantly, because the molten weld-metal
freezes very rapidly.
Through scientific
research Magna Fluxes have been
engineered to provide the super energy
necessary to alter the geometric
dimensions, break the surface tension
and spread the molten weld-metal with
incomparable force.
NOTE: When the weld
metal has a high contact angle (as in
the case of a sphere which often results
with ordinary fluxes), very little
strength is provided.
(2) Magna
Fluxes have a powerful dissolving effect
that promotes a point of total,
thermodynamic equilibrium. This is
achieved through special chemical
reactions. This takes place deep within
the metal surface. The process is one of
actually penetrating into the metal
pores and surface irregularities in
order to prepare an area of tenacious
anchorage.
(3)
Magna Fluxes cleanse the base metal.
Every welder knows that metal contains
impurities deep inside the metal
surface. The impurities are one of the
main causes of poor bonding. Magna
Fluxes actually penetrate the metal
surface, follow the metal geography and
perform powerful de-oxidizing and
scavenging operations. Then, by
depressing the melting point of these
oxides, they are floated or vaporized,
leaving behind a sterile, clean metal
'comb'
into which the molten
weld-metal will traverse and bond.
(4)
Magna Fluxes contain
micro-pulverized metals such as Barium,
Magnesium, Strontium, Boron, Zinc, Tin,
Molybdenum, Lithium, Chromium,
Tellurium, Sodium and Misch-metal. Their
super-micronized sizes give them the
ability to become liquid and bond, with
very little heat, ensuring that they
form an affinity with the inner-pores of
the metal surface. This affinity results
in a surface alloying effect which
results in an incredibly super-strong
bond which is anchored
'inside'
the metal surface.
All Magna
Fluxes meet or exceed the United States
