    Howdy Noel and others; I am a beginner metalsmith and come from an
    electronics background so it was a little confusing to me also. I'm
    comfortable with the definition that 'soldering' (soft soldering-as
    in electronics) occurs below 840deg. without the melting (puddling)
    of the parent metal(s).  Brazing ('hard' soldering - like for most
    jewelry work) is above 840deg. without melting the parent metal(s).
    Welding (fusing) involves melting or 'puddling' the parent metal.  I
    suppose these activities may or may not involve the use of flux or
    'cover' gases?
