FWIW the American Welding Society (AWS) has a basic definition of Brazing and Soldering:
Brazing and soldering share a number of features.
Both are liquid-solid state processes as they
involve molten filler metal and solid base metal, which
do not melt or mix. In both brazing and soldering, metallurgical
bonds are produced by mutual diffusion
rather than by fusion. Predominantly, the molten filler
alloy diffuses into the base metal. Some base metal is
also dissolved, diffusing into the filler metal. Although
the fundamentals of bonding are the same for both
processes, the temperature required to effect joining
determines whether the diffusion process is considered
brazing or soldering. Brazing takes place when the
metal is heated to above 840°F (450°C), while soldering
occurs below this temperature.
