Ed,
I've heard our English brothers refer to fillet brazing as "bronze welding" upon occassion. Might as well add that one to your list of terms to compare. I'm not familiar with the technical deffinition of welding since that's not what I do; but if it is technically incorrect I'm not going to debate it. If they call it just "welding" I'd be fairly certain that is wrong. I'm stabbing in the dark here, but I believe welding by deffinition means that both the parent metal and the filler material are melting, whereas with brazing only the filler metal is melted (we all hope!). I also think that in brazing the metal and the filler are different metals, where in welding they are the same or very nearly the same.
Never had any technical brazing instruction, just started doing it after having watched a few others do it. Brazing bike frames is a specific operation and most of the normal "industial" uses don't include the specific challanges presented by a lugged thinwall steel tubeular trapezius (unless you have parallel head/seat angles in which case a trapaziod) that must maintain alignment to rather close tolerances.
