It is easy to make an assertion without proof...I guess you see my point.
thanx.
I have no proof. I think that you are probably right -- welds probably are stronger (as long as the structural integrity of the tubes being welded together are not compromised). However, the question is "Is it (a properly brazed and lugged joint) strong enough for the task being asked of it?" I think history has proved that to be a resounding YES!
