Induction Brazing Aluminum AutomotiveĀ
Objective: Heat aluminum for an automotive brazing application
Material: Aluminum tubing 0.50 (12.7mm) dia, an aluminum boss 1āĀ (25.4mm) long, flux filled braze rings
Temperature: 1200 ĀŗF (649 ĀŗC)
Frequency: 370 kHz
Equipment ā¢ DW-UHF-10KW induction heating system, equipped with aĀ remote workhead containing one 1.0Ī¼F capacitors for aĀ total of 1.0 Ī¼F
ā¢ An induction heating coil designed and developedĀ specifically for this application.
Process A multi turn pancake coil is used to heat the joint between theĀ aluminum tubing and boss. The joint heats to temperature inĀ 1.5 minutes and the braze ring melts forming a clean brazed
joint.
Results/Benefits Induction heating provides:
ā¢ Hands-free heating that involves minimal operator skill forĀ manufacturing
ā¢ Flameless application
ā¢ Reliable, repeatable aesthetically pleasing braze joint
ā¢ Even distribution of heating
