Q: 

In what applications is using paste feasible?

A: 

Paste can be used for torch, induction, and furnace applications. In these applications flux is usually added to paste formulation. When using paste in a vacuum or atmosphere furnace flux does not need to be added to the paste.

Q: 

What is the proper clearance for brazing?

A: 

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.
