The invention relates to a method for mounting a fastener element (1), such as a screw or a nut, in a component (2). The fastener element (1) is provided with a deformable, cylindrical portion (3) which has an axis of symmetry. The cylindrical portion (3) is inserted in a through-hole (4) in the component (2), whereafter the cylindrical portion (3) is deformed in its longitudinal direction by means of a compressive force, so that the length of the cylindrical portion (3) is reduced. By causing the fastener element to rotate at a predetermined rotational speed so that frictional heat is generated between the contact surfaces of the fastener element (1) and the component (2), there is created a combined rivet and frictional welding joint between the fastener element (1) and the component (2). The invention also relates to a tool for mounting the fastener element in accordance with the method.
L'invention concerne un procédé pour monter un élément de fixation (1), tel qu'une vis ou un boulon, sur un composant (2). L'élément de fixation (1) est muni d'une partie cylindrique (3) déformable qui a un axe de symétrie. La partie cylindrique (3) est insérée dans un trou de passage (4) du composant (2), où la partie cylindrique (3) est déformée sur sa longueur par une force de compression de sorte que la longueur de ladite partie cylindrique (3) est réduite. En faisant tourner l'élément de fixation selon une vitesse de rotation prédéterminée telle qu'une chaleur de friction est produite entre les surfaces de contact de l'élément de fixation (1) et le composant (2), on crée un rivet combiné et un joint soudé par friction entre l'élément de fixation (1) et le composant (2). L'invention se rapporte également à un outil servant à monter l'élément de fixation conformément au présent procédé.
