Friction Welding Supplier

Anyone know any friction welding specialists that could join two driveshafts for a reasonable sum?

CPS want £114 per weld plus delivery!

theres not that many places do friction welding, thats why its so expensive.
Why does it need to be friction welded?
New prop shafts from the likes of bailey morris, and the others I forget the name of, are all migged I'm sure. Done on a lathe,

I'd be surprised if you could get low volume friction welds done much cheaper than that.

Like blake said is there a reason it can't joined in another way?

As said, that's a decent price for friction welding.

Other way is to sleeve and have welded by a certified welder.

The shear area of a friction weld would be tiny compared to a sleeved joint.

Friction welding's not a typical prototype process, so it's unsurprising nobody wants to touch them as a one off.

Don't GBEngineering only want that sort of money for a custom driveshaft?

indy - indeed, I think you are only in for another £60 for an entire custom driveshaft. Looks like i'm welding the prototype and having some custom ones made up. Just seemed like a fairly quick common process - cheers for advice

I ran sleeved shafts for years on my kitten with no issues .martin Keenan sorted me some custom ones at a very good price , worth a call as I think they were £180 for a pair and I've put 400lb FT through them no problem

That's because a propshaft is a relatively large diameter thin wall tube and the propshaft companies are typically just welding a UJ onto the end.

A driveshaft is a smaller diameter solid bar, which makes joining two bits together a much harder job; the only real options for welding are are to sleeve it and hope for the best or to friction weld it. A custom made driveshaft is certainly the best solution though.
