An apparatus (1) for friction stir welding, comprising a welding assembly (12, 13), a work-table (7) supporting the workpiece or workpieces (2, 3) to be welded, and at least one clamping means (5, 6) for clamping the workpieces to one another and/or to the work-table, or the workpiece to the work-table, respectively, during the welding operation. The apparatus also comprises a device for adjusting the position of the welding assembly (12, 13) in the height direction relative to the work-table (7) during the welding assembly movement in the longitudinal direction of the welding joint formed during the welding operation in order to provide an optimum distance between the work-table and the welding assembly. |
