Been a lot of discussion on that issue here. Technically, you are probably correct, according to the original definitions of welding, brazing, and soldering. But a common usage of the terms now is to call it brazing when the filler metal flows into the joint and bronze welding when the filler metal is also used to build up a fillet. All the custom frame building that we are talking about here (Rickman, Seeley, etc.) use the latter (bronze welding) technique. Still, calling anything using bronze filler brazing is also pretty common, at least in the US. Also sometimes called braze welding, but I don't see that one used much. I think the use of the term "bronze welding" came about to distinguish between the conventional "hearth" and torch brazing techniques used for earlier tube and lug frame construction, where all the strength comes from the capillary flow of bronze into the joint, and the later method where much of the strength comes from the built-up fillet of bronze between the fitted tube joints. SIF may have been the ones to pioneer this technique, or not, but their alloys were definitely the material of choice for it at the time.
