What is the proper clearance for brazing?
In general, a joint clearance ranging from 0.002″-0.005,” will produce sound high strength joints when flux brazing. When atmosphere and vacuum brazing, joint clearance should be 0.000″-0.002.” Care does need to be taken when brazing metals with different coefficients of thermal expansion. The amount the materials expand needs to be factored in when determining joint clearance.
