Brazing is the process of joining metallic materials using a molten filler
metal, drawn into the joint by capillary action. The filler metal is
usually a solder paste and it is placed on the parts prior to
heating. Usually, filler metal becomes molten well below the melting
point of the materials being joined.
Furnace brazing
The popularity of furnace brazing stems from the clean atmosphere
used, which mostly eliminates use of fluxes and also eliminates post-braze
cleaning. Various types of furnace are used for brazing, mostly employing
a gaseous atmosphere. The overall furnace construction is based on either
batch type or continuous operation.
Carbon Boards
The parts to be brazed are usually placed in
machined carbon boards as shown above. Carbon boards are
manufactured carbon plate, which are machined with the contour of the
piece to be brazed. The allow consistency in the brazing
process. Carbon will not breakdown in the heating and cooling
process
Materials
Most materials can be furnace brazed. All materials need to be cleaned
prior to insertion in the furnace to remove surface scale, grease and
other contaminants (high quality in, high quality out). The most widely
used fillers for furnace brazing are based on silver, copper, nickel and
gold, the latter two being most applicable to stainless steels, and heat
and corrosion resistant alloys.
