FABTECH 2012: Brazing Rings(1)
The new Sil-Fos 15 Rings are designed for brazing copper tubular components for HVAC/R installation applications. The Sil-Fos rings use a calculated alloy volume for use with standard size copper tube from 0.25 to 1.125” (6.35–29 mm). The advantage of using these rings is consistent and repeatable joint quality while controlling alloy usage. Braze rings are easy to use, minimize waste, and provide visual verification of a complete, sound braze joint. There are a few easy steps to this application: Clean the areas to be brazed; insert the ring into the fitting, the tube is inserted to seat the ring at the bottom; uniformly apply heat, and upon melting, the filler metal is drawn through the joint via capillary to the exterior surface. A witness line of alloy at the exterior joint assures that complete alloy penetration has been successfully completed.
