Induction Soldering brass and copper

Objective To heat brass and copper for soldering application on medical equipment
Material Brass ring, brass and copper pieces 5.11” (130mm) long, 4.3” (110mm) OD & 0.3” (7mm) at thickest point and solder rings
Temperature 392 ºF (200 ºC)
Frequency 306 kHz
Equipment • Power of 20kW induction heating system, equipped with a remote workhead containing two 0.33μF capacitors for a total of 0.66μF
• An induction heating coil designed and developed specifically for this application.
Process This process is completed in two steps that use a 3 turn helical coil. The first process is to solder the brass ring to the copper piece which takes 85 seconds. The second step is to solder a large brass piece to the first assembly. This process takes 50 seconds for a total process time of two minutes 15 seconds.
Results/Benefits Induction heating provides:
• Hands-free heating that involves no operator skill for manufacturing
• Even distribution of heating
• Faster process time, current process takes 5 minutes
• Consistency by using solder rings
