Induction Soldering Stainless Steel To Wire

Induction Soldering Stainless Steel To Wire With IGBT High Frequency Heating Units

Objective Heat Stainless steel connector for soldering application inĀ automotive wire harness manufacturing
Material Stainless steel connector 1.57ā€ (40mm) long, 0.6ā€ (15mm) ODĀ & 0.4ā€ (10mm) thick. Lead free solder
Temperature 392 ĀŗF (200 ĀŗC)
Frequency 352 kHz
Equipment ā€¢ DW-UHF-6kW induction heating system, equipped with aĀ remote workhead containing one 1 Ī¼F capacitor.
ā€¢ An induction heating coil designed and developedĀ specifically for this application.
Process A two turn channel coil is used for soldering the connector toĀ the wire harness. The stainless steel connector and wireĀ harness are placed in the coil for 20 seconds for the solder to
fill just the top of the connector.
Results/Benefits Induction heating provides:
ā€¢ By precisely heating the metal, the plastic shroud is notĀ directly heated
ā€¢ Reduced production cost
ā€¢ Faster process time, reduced production cost
ā€¢ Hands-free heating that involves no operator skill forĀ manufacturing
ā€¢ Even distribution of heating

Induction Soldering Stainless Steel Tubing

Induction Soldering Stainless Steel Tubing with IGBT Soldering Heating Units

Objective Heat a.125ā€ (3.175mm) diameter stainless steel tube to a 1ā€Ā diameter cylinder 1ā€ (25.4mm) tall for a soldering application
Material Stainless steel cylinder and tube
Temperature indicating paint
Lead free solder preform rings
Temperature 300-400 ĀŗF (150-205 ĀŗC)
Frequency 235 kHz
Equipment DW-UHF-4.5 kW, 150-400 kHz induction power supply,Ā equipped with a remote heat station containing two 0.66 Ī¼FĀ capacitors (total 1.32 Ī¼F).
A three-turn pancake coil induction heating coil designed andĀ developed specifically for this application.
Process Initial tests without solder ensured that the metal reaches theĀ required temperature and the heating pattern on the part.Solder preform rings are placed onto the tube at the joint. TheĀ part is placed inside the induction-heating coil heated until theĀ solder melts.
Results/Benefits Programmable and adjustable heating ramp rates achieve theĀ desired heat profile. Too fast a heat profile does not conductĀ the heat through the joint and too slow a heat cycle vaporizes
or dries the flux causing poor solder flow.
