    The American Welding Society has set up guides to define these
    terms. Soldering is joining metals by melting the filler metal only.
    Brazing is a method where the heat opens the "pores" of the  base
    metal to allow infusion of the filler metal.Welding is when you melt
    both the base metal and the filler metal to join the materials. They
    Also have defined the temperatures which control these processes. I
    do not remember what they are. I retired form the Welding supply
    business many years ago.  I do have my senior moments too. 
    What most jewelers do is BRAZING.
