Not sure where the anti-welding comes from and why DOT thinks welds are no good. Yes, it depends on welding skills. Anyway, I would weld on the shaft all day if I needed to. The main engine nozzles of the space shuttle were welded together from about 60 parts. I know, I helped build them. HP steam piping in nuclear reactors are welded, too. Welds are a good way to join metal. If you don't think so, stay out of steel framed buildings.
OP, glad you're getting it worked out.
