I do a fair bit of silver brazing with 50% silver solder. Typically high pressure brake and power steering custom fittings we need for some of the stuff we do. High temp black flux, good heat source and done right, works exceptionally well.I built bicycle frames for a few years and loved brazing, loved the look of it
however brazing is not a form of welding as the parent metals are not fused but still a very strong joint, the benefit of brazing is you can join dissimilar metals.
