Induction Brazing Steel Tube
Objective: To heat an oil suction assembly (steel tubing and filter cap) to 1,850ยฐF (1010ยฐC) within 15 seconds for a brazing application.
Material 0.125″ (3.2mm) diameter steel tube and filter cap assembly, high temperature brazing flux, copper ring.
Temperature 1850ยฐF(1010ยฐC)
Frequencyย 500 kHz
Equipment โข DW-UHF-6KW-I induction heating system equipped with a remote workhead containing 0.66 ฮผF capacitors โข An induction heating coil designed and developed specifically for this application.
Process A two-turn, specially-contoured helical induction coil is used to heat the tube assembly near the joint area. A copper ring and high temperature flux are then applied to the joint area. Power is applied for 15 seconds until the braze flows.
Results/Benefits Induction heating provides:
โข Easy loading and unloading of parts
โข Heat very precise areas within production tolerances
โข Hands free heating that involves minimal operator skill for manufacturing
