Definition
Brazing is a metal joining process
which utilizes the inter-atomic
attraction between two pieces of
metal to form a bond that approaches
parent metal strength. This is
accomplished by “wetting” the metals
to be joined with molten metal
which, upon cooling, forms the
joint.
> 800 DegF is termed Brazing and <
800 DegF is termed Soldering
Welding differs from brazing in
that the base metals to be joined
are molten at the moment of joining.
Aluminum filler metals are used to
braze aluminum base metals using
various methods, the most common
being:
|
• |
Salt dip bath |
|
• |
Vacuum |
|
• |
Flux (either torch or
furnace) |
