An apparatus is proposed for connection of workpieces using the friction stir welding method, with a shaft ( 33, 33 ') which can be driven such that it rotates and at whose end remote from the drive end of the shaft a pin-like projection ( 8 ) is arranged, at whose end a first stop, which is formed by a first shoulder ( 6 ), is arranged, with the first shoulder having a diameter which is larger than the diameter of the pin-like projection ( 8 ), and with a second stop ( 7, 7 '), which is formed from a second shoulder and is arranged such that the workpieces ( 19 ) to be connected can be enclosed between the stops ( 6, 7, 7 '), in that at least one of the stops can be moved translationally in order to enclose the workpieces ( 19 ) with a predetermined force in the direction of the other stop. The apparatus ( 1 ) is in this case designed such that the second shoulder ( 7 ) or the second stop is designed such that it can be rotated, and the first and the second shoulder ( 6, 7 ) or the first and the second stop are designed such that they can be rotated in the opposite sense.
