Calculating Ring Volume

Posted by Lucas-Milhaupt Brazing Experts on Nov 21, 2012
Importance of Ring Volume One factor that may impact the strength of a brazed joint is the depth of alloy penetration into the joint. If an operator does not apply enough alloy to the assembly, the final part will not have the ideal strength and/or leak tightness characteristics for a brazed joint. ...
