Brazing Brass Pipe With Induction

Brazing Brass Pipe With Induction 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: 350 kHz Equipment DW-UHF-10KW 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
