Abstract (en)
[origin: WO2009126981A1] The invention relates to a device (1) and a method for connecting at least two workpieces (7, 8) by friction welding. The device here comprises an axis (10) which can be driven in a rotating manner and on which a friction welding tool (1) is arranged, wherein the friction welding tool (1) has at least one pin-like tool (2), which can be driven in a rotating manner and is surrounded by at least one hollow cylinder (3), which can be driven in a rotating manner. The friction welding tool (1) can be moved along its axis of rotation (10) by the plastifying workpieces (7, 8), wherein the pin-like tool (2) and the hollow cylinder (3) can be moved independently of each other in the axial direction. The hollow cylinder (3) has on its side facing the at least one upper workpiece (7) a detachable friction liner (6) with a friction surface (5).
