Induction Soldering Steel Parts,Wire,Tube,Pipe and Rod with IGBT Induction Heater
Objective To heat a special steel housing to 500(260) ºF(ºC) for a soldering application
Material Steel housing Solder wire and flux
Temperature 500(260) – 550(287.8) ºF(ºC)
Frequency 200 kHz
Equipment DW-UHF-6kW, 150-400 kHz solid state induction power supply with a remote heat station containing two 0.33 mF capacitors (total capacitance 0.66 mF). A custom-designed induction heating coil.
Process A two-turn induction coil is used to deliver the heat energy into the steel housing. A small diameter solder wire is used to form a solder ring for the assembly process. Solder flux is applied
generously to the joint area. Induction power is applied to the assembly until the solder ring flows into the joint. The same coil is used to solder multiple locations on the housing.
Results/Benefits · Ability to solder multiple locations with one coil. No need to change coils.
