They are very dangerous, if not put together right before inflating, they can come apart violently, shooting the ring off fast enough to kill. This is why no tire shops will touch them, to much risk and liability. Several years ago the place I used to work had someone killed by one. The ring flew off while he was inflating it and it caught him in the chin picking him up and throwing him back about 6 feet. As for welding them, it's not possible the correct relief to get the tire on it is not there, for lack of a better description it's kinda like a true bead lock.
