I retired from Caterpillar and we back in the late 70"s used the same type 
welding only we called it "Inertia Welding" we welded track roller half's 
together this way along with many other shafts together. 
  One piece was held solid while the other would spin using a motor and 
weighted holding fixture, when it reached a pre-set speed the motor power would 
cut off and then the parts were forced together making the weld.
