摘要： The invention relates to a friction-stir welding device for joining workpieces 1, 2, comprising a welding pin 3 that can be rotated about the welding pin central axis 9 by means of a drive and comprising at least one clamping device for clamping the workpieces 1, 2 to be joined. The invention is characterized in that the clamping device comprises at least two clamping elements 10, 11, each of which has an undercut guide track 12. The guide tracks 12 are arranged parallel to one another and parallel to a joining region 8. A sliding element 13 is arranged between the clamping elements 10, 11, said sliding element being retained against the workpieces 1, 2 by the guide tracks 12 and being movable along the guide tracks 12 in a translational manner. The sliding element 12 is provided with an opening 14 through which the welding pin 3 is passed. The invention also relates to a method for friction-stir welding using the aforementioned device.

摘要： The present invention relates to a device for contactlessly gripping, holding and positioning, preferably contact sensitive, components. The device is provided with the following characteristics: sound producing means (2a) for producing levitation sound waves (3) which can be used for keeping the component (1) in suspension in a selected nodal point of energy (4) and in a holding level (5), whereby the nodal point pertains to the sound waves (3). The sound producing means (2a) are arranged in such a way that the planar edge sections (1a) extend only partially into the active area of the sound-radiating areas (6) belonging to the sound producing means (2a) and that the sum (A) of the sound-radiating surfaces (6) belonging to the sound producing means (2a) is smaller that the surface (B) of the component (1).
