Perhaps brazing a broken frame on tour would be better than trying to weld it?

Maybe. At least it is a lower temp more forgiving process. Also someone previosly mentioned slip joining and precise fitment. That fails to consider the possibility of using fillets. There is such a thing as building up fillets that serve in the place of lugs in frame construction. Building up a thichness of bronze can be used in repairing as well. Poorly done it may ruin the temper of the tubes, but as an emergency repair I'd take my chances with it. I have fabricated or repaired a lot of stuff with an oxyacetelene torch and either brazing or silver solder. I've even done a little welding with the torch way back in the day.
