Silver Solder vs Brazing

[tecman]

There has been a thread about solder vs brazing. I have been using 15% silver solder for years for line joints. Some people call silver solder brazing, and others call it soldering.

What do most of you use for "brazing" ? A silver solder rod, or a non-silver brass alloy rod ?

Am I wrong or is most of the references to brazing here actually a silver-copper rod rather than a non-silver type ?

Definitions
What is the difference between soldering, brazing and welding?

Soldering - The AWS defines soldering as a group of joining processes that produce coalescence of materials by heating them to the soldering temperature and by using a filler metal (solder) having a liquidus not exceeding 840ºF (450ºC), and below the solidus of the base metals.

Brazing - Brazing joins materials by heating them in the presence of a filler metal having a liquidus above 840ºF (450ºC) but below the solidus of the base metal.

Welding - In welding, fusion takes place with melting of both the base metal and usually a filler metal.
