The '''Brazing Furnaces''' ensure consistent brazing results by offering superior temperature and atmosphere control.

Furnace brazing is a metal-joining process  whereby a filler metal or alloy is heated to melting temperature above  450 °C (840 °F) and distributed between two or more close-fitting parts  by capillary action. The filler metal is brought slightly above its  melting (liquidus) temperature while protected by a suitable atmosphere  or brazing flux. When the part reaches the liquidus temperature of the  filler metal, the filler metal wets a thin layer of the base metal.

As the temperature of the part being brazed is lowered to below the  liquidus temperature of the braze alloy, the part being brazed is cooled  rapidly to form a brazed joint. By design, the melting temperature of  the braze alloy is lower than the melting temperature of the materials  being joined. Furnace brazed joints are generally stronger than the  individual filler metals used due to the geometry of the joint as well  as to the metallurgical bonding that occurs.

==='''Advantages'''===

There are varied reasons which makes furnace brazing preferable over other brazing methods.

* Furnace brazing  has a controlled heat cycle minimizes or eliminates distortion.

* Furnace brazing  eliminates the need for post braze cleaning operations
