Title (EN) FRICTION STIR WELDING APPARATUS AND METHOD WITH THERMAL CONTROL
(FR) APPAREIL ET PROCÉDÉ DE SOUDAGE PAR FRICTION-MALAXAGE À COMMANDE THERMIQUE
Abstract:
(EN) A Friction Stir Welding (FSW) apparatus (200) for welding work-pieces (224) is provided. The FSW apparatus includes a pin tool (212) with a penetration axis (204) along an axis of penetration of the work-pieces (224). The FSW apparatus (200) comprises further a thermal control unit (232) comprising at least one heating element (216) in thermal contact with the work-pieces (224), the at least one heating element (216) arranged along the penetration axis (204) to effectively plasticize the work-pieces at a weld region (250), whereby a plunge force required by the pin tool (212) to penetrate the weld region (250) is reduced.
(FR) La présente invention concerne un appareil de soudage par friction-malaxage (FSW) (200) pour souder des pièces à usiner (224). L'appareil de FSW comprend un outil à broche (212) ayant un axe de pénétration (204) le long d'un axe de pénétration des pièces à usiner (224). L'appareil de FSW (200) comprend en outre une unité de commande thermique (232) comprenant au moins un élément chauffant (216) en contact thermique avec les pièces à usiner (224), le ou les éléments chauffants (216) étant disposés le long de l'axe de pénétration (204) pour plastifier efficacement les pièces à usiner au niveau d'une région de soudure (250), moyennant quoi une force de plongée requise par l'outil à broche (212) pour pénétrer dans la région de soudure (250) est réduite.
