Typically the brazing process depends first on the two materials being joined then on the intended use. After that you would have cost and time considerations.
If you could identify the materials you wish to join and the intended application I would be happy to offer whatever help I could.
You are correct of course but we look at it as having significant differences other than just the temperature range. Two things that come to mind are that soldering seems to be used more for fixturing and brazing more for joining. 1. In a good braze joint you create both a chemical and a mechanical bond while in soldering the bond is more likely to be purely mechanical. 2. There seems to be some sort of naturally occurring gap between soldering temperatures and brazing temperatures. As an example of naturally occurring changes, we sort of think things start behaving differently somewhere below zero F and somewhere above 1500 F. These are indefinite ranges but seem to be important operationally.
On a much more practical level we see folks trying to braze with solder fluxes and that is generally pretty unsuccessful.
Having said all this I will admit that your answer may be better than mine depending on what is behind the question but I though it important to introduce some other considerations just in case they might prove helpful.
