An introduction to vacuum furnace brazing technology - Part 2: further technical considerations and brazing hardware
During use all vacuum brazing furnaces are pumped continuously. As a result, both the total pressure and the composition of the residual atmosphere are undergoing continuous change as the furnace goes through its programmed cycle. The significance of the continuous change in the residual atmosphere is usually seen by the furnace operative(s) when 304 austenitic steel is being brazed.
