The invention relates to a method and to a device (10) for linking at least two adjoining work pieces (11, 12) by friction welding. Said work pieces (11, 12) include a zone of connection (13) between them that comprises a rotation-driven shaft (14) at whose end (15) facing away from the drive a pin-like projection (16) is provided which at least partially plastifies the zone of connection (13) of the work pieces (11, 12) when rotating and contacting said zone of connection (13). Said pin-like projection (16) can be displaced in a substantially longitudinal direction relative to its axis of rotation (17) so that it traverses the plastifying material (30) of at least one first work piece (11) oriented in direction of the pin-like projection (16) and at least partially extends into a last lower plastifying work piece (12). The pin-like projection (16) is then retracted from the work pieces (11, 12) so that the plastifying material (30) of all work pieces (11, 12) is combined.
