Is this an acceptable process?


Yes, a company I worked for had a friction welding division and that's
how they did it.

I think not, with the way it stopped the lathe. Maybe if the fixed piece
was allowed to spin before stopping the motor there would have been less of
a jolt.


The machine is not a lathe. The headstock is similar, the tail stock
pushes one half of the piece under enormous pressure against the other
half. The weld slag at the junction can be a bitch to remove.
