How to Flux Brazing Joints

Posted by Lucas-Milhaupt Brazing Experts on Mar 30, 2018
Flux is a chemical compound applied to the joint surfaces before brazing. Flux is essential in the brazing process because it prevents oxides from forming and inhibiting the metallurgical bond in brazing. Oxides are the result of chemical combination between the hot metal and oxygen in the air and ...
