Title (EN) METHOD AND APPARATUS FOR JOINING METALS
(FR) PROCEDE ET APPAREIL D'ASSEMBLAGE DE METAUX
Abstract:
(EN) The present invention discloses methods and apparatus for joining of two workpieces (20). The present invention includes special preparation of the joining ends of the two workpieces (20) to be joined. Methods of the present invention include delivering a high current, low voltage pulse to a pair of workpieces to be joined while applying and maintaining a constantly high load on said workpieces (20) to thereby join the workpieces (20).
(FR) L'invention a pour objet des procédés et un appareil destinés à l'assemblage de deux pièces à usiner (20); elle comprend une préparation spéciale des extrémités d'assemblage des deux pièces à usiner (20) qui doivent être assemblées. Selon les procédés de cette invention, on fournit une impulsion de basse tension et de forte intensité aux deux pièces à usiner (20) devant être assemblées et l'on applique aux pièces en question une charge élevée et constante pour les assembler.
