Patent

CA 2737261

The invention relates to a method for joining at least two components by inductive high-frequency pressure welding, namely a first component with a first material structure having a first hardness and a second component with a second material structure having a second hardness which is smaller than the first hardness. For this purpose, both components are inductively heated in the region of the joining surfaces and are subsequently pressed together by a compressive force. According to the invention, the joining surface of the first component having the first hardness, which is greater than the second hardness of the second component, is pre-contoured in a spherical, conical or convex manner prior to joining the two components.

L'invention concerne un procédé d'assemblage d'au moins deux éléments, notamment un premier élément présentant une première structure de matériau d'une première dureté et un deuxième élément présentant une deuxième structure de matériau d'une deuxième dureté inférieure à la première dureté, par soudage par pression et par induction à haute fréquence, selon lequel les deux éléments sont chauffés par induction dans la zone de surfaces d'assemblage puis pressés ensemble par l'exercice d'une force de compression. Selon l'invention, les contours de la surface d'assemblage du premier élément, qui présente une dureté supérieure à la dureté du deuxième élément, sont façonnés sous forme bombée, conique ou convexe avant l'assemblage des deux éléments.
