An aerospace manufacturer is joining stainless steel tubes using a brazing process. The filler metal selected has a melting range of 890°C to 900°C, while the base metal melts at 1450°C. The joint design specifies a clearance of 0.08 mm. Which combination of process parameters is most likely to achieve a sound joint with optimal capillary action and minimal oxidation?
Brazing at 920°C with a borax-based flux in a controlled argon atmosphere
Brazing at 940°C with a rosin-based flux in a vacuum
Brazing at 860°C with a fluoride-based flux in open air
Brazing at 900°C with a chloride-based flux in nitrogen atmosphere
Brazing at 920°C with a borax-based flux in a controlled argon atmosphere
