Yes, trying to metal weld near brazing will be difficult. And it will be extremely difficult to remove all the braze from around a tube end.
I tried to warn one of my old aviation bosses that he should keep his welding rods and his brazing rods separated better and more distinctly. Shortly after I moved on he grabbed a brazing rod while welding on a custom bracket onto a longeron of one of the Travel Air biplane fuselages we had made from scratch. I sure am glad I was not there to hear the cussing!! If I remember right it took the two of us working full time about a month to make one. He had to splice that fuselage and I think he never sold that particular one. He was amazed just how far he had to get away from the brazing in order to get a good weld. I wasn't. I had run into that situation before!
