I've stuck 1in angle iron together and had it stay stuck under load. I count that as welding, with some pride.
but then i've seen folks weld together an excavator that broke (in half) halfway up the main arm. and then seen the machine finish the job with their repair. that's real welding, so i can only claim "small".
Technically speaking, welding is when you've melted the two pieces together so they form an integral piece. Brazing is when you're "gluing" two pieces together using the metal of the brazing rod as the glue.
Brazing is not necessarily a weaker bond than welding, depending, but is usually done either as a temporary repair until welding can be done later (because you can braze with a blowtorch instead of a welding machine), or when you're bonding two metals that are different enough that welding is not possible.
Technically speaking, soldering is a form of brazing.
