I am aware brazing is very popular among steel bike builders and that brazing V.S. welding steel can be somewhat hotly debated among frame builders. However, I cannot find much info on brazing vs welding aloy bikes. This seems rather odd to me, as there is the potential for some interesting characteristics to be introduced into the bike with brazed joints.
Therefore, I am wondering, what are the potential advantages and disadvantages to brazing aloy bikes? Are there any fatigue benefits like with brazed steel?
