I would normally call joining with silver alloy silver soldering rather than brazing which suggests the use of brass or bronze as the filler. Mind you I haven't done this stuff for forty years and so the nomenclature may have changed in that time.

Silver soldering is technically correct, as the "filler/joiner" is a different metal from the parts to be joined and the parent metal is not melted and fused as in "proper" welding.

Sometimes the term "silver brazing" is (loosely) used to differentiate the use of a gas torch as opposed to the "other" sort of soldering, such as that I occasionally do on electronic equipment or what plumbers used to do before the advent of PVC pipes.
