Infrared brazing utilizes focused light energy (typically from high intensity quartz bulbs) to heat components to brazing temperature.
Infrared Brazing Advantages
The advantages of infrared brazing are similar to those offered by induction brazing:
Infrared brazing’s fast thermal cycle achieves an optimized microstructure.
Non-metallic components may be heated, because energy transfer does not depend on generation of electrical currents within the assembly to be brazed.
In infrared brazing, a transparent quartz chamber or retort normally surrounds the assemblies. In some instances, a thin-walled refractory tube may also be used for atmosphere containment, but heating rates are generally slower.
The fast thermal cycle achieved in infrared brazing achieves an optimized microstructure.
Rapid heating and cooling rates are possible, which can make infrared brazing suitable for meeting high production requirements.
