BRAZING RODS AND FLUXES If the bonding temperature is below 400°C the method is termed Soldering. If the bonding temperature is above 400°C the method is called Brazing. Brazing can further be divided into Capillary brazing/Silver brazing and Braze welding.

In Capillary Brazing the alloys are thin flowing in consistency (Silver brazing) and they are ideal for use in capillary joints.

In Braze welding the alloys are mostly thick floating in consistency and the joint preparation like in welding.

Brazing Methods Soldering

Capillary Brazing

Paralell surfaces with minimal space between.

400°C

Brazing

Brazing “Welding”

Space between surfaces similar to that used in gas welding.
