Not usually; the whole point of most silver solders is that they have a low
melting point compared to, say, brazing alloys, and can be used with a
butane or propane torch in air.

The cadmium-free ones, though, are used because they don't adversely affect
other materials (eg titanium) and they have rather higher melting points,
similar to brazing alloy or even higher.
