Brazing Brass

Brazing Brass

Brazing Brass

(OP)
I just completed my participation in a Kaizen Event involving a brass brazing oepration.  I learned some neat things about the process, and I'll post them here as an (unsolicited) tip for others:

1. Temperature control is vital.  Heat both parts to the same temperature.  Minimize air space between mating parts.

2. Cool your parts after brazing.  A good ratio is that for every 4 heat stations, have 1 cool station.

3. Fluxing is the most important part of the operation.  Initial quality is strongly associated with proper consistency and application of flux.  Don't ignore this.

4. Don't use compressed air in the brazing torches.  Compressed air tends to be far too moisture laden (even when sufficently dessicated for other shop uses) to be effectivly control in a brazing operation.  Try a forced air blower system.  System control will be much tighter.
