I remember my bike frame was brazed together when I was a kid. The tubes were fitted into the connecting fittings and you could see the brass around the joints when the paint was removed.

yes, brazing into the connectors would be strong enough, if there are connectors... a really great brazer can get butt brazing that's almost as strong as a weld, none that good exist these days, probably... with connectors, you could get as much strength from bolting the connectors on, but they would wiggle and flex, torch some filler in to make it secure, even lead solder could do the same with strong connectors.

brazing is much like glue, more surface area=stronger connection, in a welded connector, there's a LOT of surface.

I would consider migrating to a mig rig for this kind of work. Unless you're a very good brazer, it's a recipe for disaster, of the kind that involves your long term health. As noted in other responses, a properly done braze is quite strong, but a weld is far better.

. Brazed motorcycle frame were common back in The Good Old Days when engines were 15HP max and top speed was around 40mph. A Q&D search of the Web turned up no mention of a modern frame being brazed.
. Brazed bicycle frames are very common, but, actually doing the job is, IMNSHO, one of those "If you have to ask, you don't need to mess with it" things.
Correct. Brazing done properly is very strong. But the keyword there is done properly.

I don't know if you are talking about motorcycles or bicycles, but in either case, if you want to braze the frame, no.
If your intention is to braze on some tabs or brackets for mounting lightweight accessories, if done properly, it shouldn't be a problem.
A broken frame is no fun, I have some forty year old scars from a broken frame on an old Triumph motorcycle.

Unlikely. Weld.
