A method for joining a highly electroconductive core element that mainly consists of copper to a jacket element made of refined steel, the method comprising inserting the electroconductive core element and a joining element that consists mainly of tin into the jacket element, and thermally treating a juncture area of the elements to be joined at a temperature sufficient to create a metallurgical joint from tin bronze between the electroconductive core element and the refined- steel jacket element.
L'invention porte sur un procédé visant à assembler une partie centrale (2) hautement électroconductrice à une partie de revêtement en acier raffiné (1). Dans ce procédé, une partie centrale (2) hautement électroconductrice telle qu'une barre de cuivre et un composant de raccordement (3) sont placés à l'intérieur d'un revêtement (1) plus pauvre en électroconductivité et sont chauffés et traités au moins au niveau de l'assemblage des pièces de façon à former un lien métallurgique entre la partie centrale (2) électroconductrice et le revêtement d'acier raffiné.
