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. | 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.

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. | 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.
