Induction Brazing Brass Trap Block

Objective Block is heated to 1400°F to braze trap tube to assembly
Material brass block and pre-formed tubes
braze pre-forms
Temperature 1400 ºF (760°C)
Frequency 357 kHz
Equipment Power of 20kW induction heating system including
• Coil: custom-designed 2-turn split-helical
• Workhead: contains two 1.0μF capacitors (0.5 μF total)
Process The brass parts, braze pre-form and flux are assembled and located within the custom-designed coil. Induction heating of the joint is accomplished in 45 seconds.
Results/Benefits Economy: induction heats only the material within the coil; no energy is wasted heating the surrounding materials and air; no flame or gasses required for heating
Control: process lends itself to the use of braze pre-forms;
process easily adapted to automation
Efficiency: energy is expended only during the joint formation.
