Question:We have a question relative to extending the expiration date on braze paste. Do you know of an industry standard that we could reference? Is there a particular rule of
Cleaning Fluxes After BrazingThe ONLY solvent that should be used for removing flux residues from the surface of the parts being brazed is HOT WATER. The hotter the water, the
Brazing fluxes are compounds that are designed to be put onto metal surfaces in
order to protect those metal surfaces from oxidation during a brazing process
that is being conducted in open air.
Let me make two important statements right at the start: 1. Surface-oxidation of metals will prevent effective brazing. 2. Brazing filler metals (BFMs) do not like to bond to (or flow over) oils, dirt, greases or oxides on metal surfaces.

Questions still arise about the difference between certain grades of stainless steel, such as 304 versus 304L, when it comes to brazing. So, let's take a brief look at this subject once again.
Over the years, I've encountered a number of situations where brazing shops have had difficulty brazing 321 stainless, even though they have no difficulties brazing 304L items.
Figure 1. Cap dimensions do not match tube top. I published a four-part article called "Voids in Brazed Joints" back in early 2009. Recently, a reader, Damian, noticed that more
