There is a further confusion regarding the names of solders. Now that traditional lead-tin solder (or soft solder, properly) has been overtaken by lead-free alternatives which often include silver in small amounts, people have been calling the new silver bearing soft-solder alloys 'silver solder'.
This is confusing because in the past, silver-solder was used to describe brazing alloys with quite a lot of silver (usually 50% or more) which have a much higher strength, and higher melting points, than any version of soft solder. Such silver solders can also be called 'hard solder' as they are much less easy to cut with a penknife.
Even the term brazing is confusing, as it should mean using brass (as in brazen images) but the term is also used for joints made with melted bronze, as well as other non-zinc-containing alloys.
I'm not sure there is a universal clear set of terms used for the various ways of 'joining by melting something else into the joint' – I am just pointing out the confusion that can be caused, currently.
