Abstract: An automated method of brazing to join two metal parts together at a joint with a braze alloy. The two parts are moved to a brazing station and maintained in a fixed position. The two metal parts are heated at the joint at a high heat rate to a predetermined temperature which exceeds the temperature that would melt the braze alloy and less than a temperature that would cause degradation of the metal parts. The temperature of the metal parts in close proximity to the joint is detected and when the first predetermined temperature is reached, the heating rate is reduced to a lower heat rate sufficient to keep the braze alloy in a liquidous state. The braze alloy is introduced to the joint between the two metal parts while they are being heated at the lower heat rate to join the two parts together and then the joined two metal parts are removed from the brazing station.

Abstract: Apparatus to apply brazing flux to a joint between two vertically oriented parts. A reservoir containing liquid brazing flux is in liquid flow communication with a pump capable of metering a fixed amount of flux when actuated. A nozzle in liquid flow communication with the pump has a housing with an outer casing and an inner casing spaced from the outer casing to form a passageway. The inner casing is open at one end to receive the parts to be joined and has two spaced apart opposing side walls with ports in each side wall in liquid flow communication with passageway. The nozzle and parts are moved relative to each other to position the joint between the two parts adjacent the ports in the side walls of the inner casing. Actuation of the pump will deliver the fixed amount of liquid brazing flux to the joint.
