in theory, yes. as pointed out by others, there's often a tiny flat
spot where the weld flashing is machined off, and using a truing stand
like a ts2 doesn't exactly emphasize the problem, but with every welded
rim i've built, it's needed higher tension for the 2 spokes at the join.
i build with an attachment to my ts2 so i have a proper handle on radial
trueness, not just lateral, which is all that stand really does.
