摘要

Piston rod connection for connecting a piston (5) to a piston rod (1), comprises a receiving part (3), and a head part (2) of the piston which is rotatably supported in a recess (4) of receiving part, and is connected by a friction-welded joint with the piston. An independent claim is also included for producing a piston rod connection for connecting the piston to piston rod.
