I have a buddy who worked rebuilding CV's for a large remanufacurer for a number of years. I'll bug him a bit about this, I'm sure he will have some good input, and he's local and he has an Electric Jeep project in the works 
My first thoughts are that you'd have to have the OD of the CV's turned down a bit to make a consistant diameter, then have a sleeve made so they can be pressed in to assure concentricity and cylindricity. I have no idea how thick and how long that sleeve should be... There are specific techniques for welding this type of joint as well. I'll look in my handbook for some inspiration. Yes, I'd want a bigger welder for this. It'd cost about 6K for one big enough... |
I gotta say, while I've never personally had to do this, I've seen a bunch of them done on custom projects, and hardly ever done with much more than measure/weld.
In fact, davidsfarm (youtube god with a TDI Caravan) did it, I believe, only using the stick axles from the Caravan and the inner flanges from the TDI by sliding the Caravan stick into the tube welded to the TDI flange, then ensured they were square and welded them.
I don't particularly see a need for anything more than accurate measuring and decent weld penetration (I would think that if you can weld 1/4" plate, you're fine) along with a re-balance after completion. I don't really have enough experience to make a recommendation, but I'd suggest stitch welding (many spots all the way around) over bead welding it.
