A method for making a joint between copper or copper alloys and austenitic steel alloys, in which method in between the junction surfaces of the objects to be joined together, there is arranged at least one intermediate layer, so that the junction surfaces in cluding their intermediate layers are pressed together, and at least the junction area is heated in order to create a diffusion joint. In the method, there is brought a first intermediate layer (3) on the junction surface of the steel object (2) or against said surface, mainly in order to prevent the nickel loss from the steel object (2), and at least a second intermediate layer (4) on the junction surface of the copper object (1) or against said surface in order to activate the creation of a diffusion joint.

Ce procédé de réalisation d'un joint entre du cuivre, ou des alliages de cuivre, et des alliages d'acier austénitique, consiste à placer entre les surfaces de jonction des objets à assembler, au moins une couche intermédiaire, de façon que les surfaces de jonction, et notamment leurs couches intermédiaires, soient pressées ensemble, et à chauffer au moins la zone de jonction de façon à créer un joint par diffusion. Dans ce procédé, on place une première couche intermédiaire (3) sur la surface de jonction de l'objet en acier (2), ou contre cette surface, de manière à empêcher la perte de nickel à partir de l'objet en acier (2), et on place également au moins une seconde couche intermédiaire (4) sur la surface de l'objet en cuivre (1) ou contre cette surface, de manière à activer la formation du joint par diffusion.
