Brazing Steel To Steel Pipe With Induction
Brazing Steel To Steel Pipe With Induction
Objective: To braze O-ring Face (ORFS) sleeve or male connector to a steel tube.
Material
• Steel tube, 1 inch (2.54 cm) OD
• O-ring Face Seal sleeve and a male connector fittings
• Preform braze rings
• White SureFlow flux
• Steel support mandrel
Temperature 1300 ºF (704 ºC)
Frequency 200 kHz
Equipment
• DW-UHF-20KW induction heating system, equipped with a remote workhead containing two (2) 1.5 μF capacitors (for a total of 0.75 μF).
• An induction heating coil designed and developed specifically for this application.
Process A four-turn 2.75 inch (7.0 cm) ID helical coil is used for heating both the steel tube and the ORFS sleeve or the ORFS male connector. This coil is designed to braze either the sleeve or male connector to the tube. The parts to be brazed are assembled with flux and heated for 45 seconds. Pressure is applied to the tube to make sure it is inserted fully into the fittings as the braze ring flows.

Annealing Metal Stamp With Induction
Annealing Metal Stamp With Induction
Objective: Induction Heating the opposite end of a metal stamp so that it mushrooms instead of cracks/splits when struck by a hammer.
Material S-7 steel of varying rectangular cross sectional sizes
Temperature 1400-1800 ºF (760-982) ºC
Frequency 300 kHz
Equipment DW-UHF-10KW, induction heating system, equipped with a remote heat station containing two 1.5 μF capacitors for a total of 0.75 μF and three different induction heating coils designed and developed specifically for this application.
Process One five-turn and two four-turn helical coils are used to heat the end of stamps to the required temperature. Two part sizes can be run in each of coils, using the same machine settings except for cycle time. Cycle rates dependent upon the crosssection size. The 3/8" (0.9525 cm) square size is has a rate of below 10 seconds. The rate for the middle size, ½" – 1 ½ " (1.27 - 3.81 cm) is 30 to 60 seconds. A 1" (2.54 cm) square part takes approximately two minutes. Fixturing can influence the length of the cycle time required. For shorter heat times a larger power supply may be used.
Results/Benefits Precise heat only to the area that needs annealing is more efficient and repeatable than heating with a torch.
