ABSTRACT:
This invention is directed to a control system and method of vacuum brazing of aluminum workpieces in a chamber wherein the combination of the partial pressure of water and the partial pressure of oxygen is adjusted to be within a determined desired combination pressure range as a function of the temperature within the chamber as the workpieces are heated up to a temperature of about 500.degree. C.
