With tens of thousands of pounds per square inch on the
bolts it's unlikely anyone needs to bond across joints for
any reason. It's just a waste of time.
Think of all that downward pull trying to shear a bolt with
a thin tower wall bearing on the surface.
The only joints with anything close to low pressure per
square inch low pressure are flange joints, and they are
only a problem when prepainted if the bolts don't push
through the paint.
He could clamp across those joints with anything from string
to diodes to gold, and the path would be through the bolt
areas with all the sheer force anyway.
