Induction Brazing Brass Faucet

Induction Brazing Brass Faucet

Objective Brazing two joints on a brass bathroom faucet assembly
Material Brass bathroom fittings 1” OD, brazing rings, flux
Temperature 1148 ºF (620 ºC)
Frequency 90 kHz
Equipment • DW-UHF-30 kW induction heating system, equipped with a remote workhead containing eight 1.0 μF capacitors for a total of 8.0 μF
• An induction heating coil designed and developed specifically for this application.
Process A two turn C shaped coil is used to braze the faucet assembly.
The braze rings are placed at the joint, the parts assembled and fluxed. The first braze joint is heated for 30 seconds and the braze ring flows. The assembly is rotated & the second joint is heated for 30 seconds to flow the braze ring. The two brazes are completed in 60 seconds.
Results/Benefits Induction heating provides:
• Faster, repeatable and consistent results
• Localized heat produces neat and clean joints
• Hands-free heating that involves no operator skill for manufacturing
• Even distribution of heating

Brazing Brass to Aluminum with Induction

Brazing Brass to Aluminum with Induction

Objective: Copper ‘tees’ and ‘ells’ are to be brazed to the aluminum body of a refrigeration valve

Material customer’s valve copper fittings braze

Temperature 2550 ºF (1400°C)

Frequency 360 kHz

Equipment DW-UHF-10KW induction heating system including a workhead containing two 1.5μF capacitors (total 0.75μF) and a three-turn helical coil

Process The valve is placed inside the coil and RF power is applied until the part is heated to the required temperature and the braze is seen to flow into the joint. Two tube sizes were run using the same induction system settings with differing cycle times.

Results/Benefits • energy is applied only to the zone to be heated • heating of the joint/braze is uniform and repeatable
