Thread: Nitrogen while brazing opinion
06-22-2005, 10:09 AM #1
When brazing with a nitrogen purge, I always try to have the nitrogen exit the fitting that I am brazing. My feeling is that minimizes the possibility of heat damage to the gas hose and it also helps carry heataway from the work area.
Anybody purge "into" the brazed joint ? Are there any opinions on the methodology ? Anybody see any other pros/cons to other ways of doing it ?
