Induction Brazing Aluminum Automotive

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