Induction Brazing Steel Tube

Induction Brazing Steel Tube

Objective: To heat an oil suction assembly (steel tubing and filter cap) to 1,850°F (1010°C) 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 1850°F(1010°C)

Frequency 500 kHz

Equipment • DW-UHF-6KW-I induction heating system equipped with a remote workhead containing 0.66 μF capacitors • 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:

• Easy loading and unloading of parts

• Heat very precise areas within production tolerances

• Hands free heating that involves minimal operator skill for manufacturing
