soldering steel to brass - induction heating machine manufacturer

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.

Soldering Steel To Brass With Induction IGBT Soldering Heater

Objective Heat an assembly of small, gold-plated steel connectors to a brass block.
Material Approx. 1/8” (3.2mm) diameter gold-plated steel connectors, 1”(25.4mm) square x 1/4” thick brass block
Temperature 600°F(315.6ºC)
Frequency 240 kHz
Equipment • DW-UHF-6kW induction heating system equipped with a remote workhead.
• An induction heating coil designed and developed specifically for this application.
Process A two-turn helical coil is used to provide uniform heat to parts assembly. Solder paste and flux are applied to the joint area and power is applied for 20 seconds to solder the parts. Proper
fixturing is needed to hold the parts in position.
Results/Benefits Induction heating provides:
• Rapid, localized heating to specific regions of part
• Neat and clean joints
• Flameless processing
