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.

L'invention porte sur un appareil (1) de soudage par friction à mouvement cyclique, cet appareil comprenant un ensemble de soudage (12, 13), une table porte-pièces (7) supportant la ou les pièces (2, 3) à souder, et au moins un dispositif de serrage (5, 6) destiné à serrer les pièces les unes contre les autres et/ou contre la table, ou de bloquer la pièce contre la table, respectivement, lors de l'opération de soudage. L'appareil comprend également un dispositif permettant de régler la position de l'ensemble de soudage (12, 13) dans le sens de la hauteur par rapport à la table porte-pièces (7), lors du déplacement de l'ensemble de soudage dans le sens longitudinal, de façon à obtenir une distance optimum entre la table porte-pièces et l'ensemble de soudage.
