Brazing is a process that is used to
bind similar or dissimilar materials by melting a filler metal or alloy
that is placed between the components being joined. Generally, brazes
are filler metals or alloys that melt at temperatures above 450oC.
These molten materials are then distributed between two or more closely
attached sections by capillary action.
Unlike welding, brazing does not melt the workpiece. At its liquid
temperature, the molten filler metal interacts with a thin layer of the
base metal, cooling to form an extremely strong, fastened bond or joint.
The brazed joint becomes a fusion of different layers, which are
metallurgically linked to each other.
The process of brazing creates an extremely stronger joint and is
frequently used to join metals other than steel, such as brass. Brazing
can also be used to apply coatings to parts in order to reduce wear and
protect against corrosion.
