An elongate first component (1) for friction joining to a second component (2) by urging the components together while causing relative heat generating movement between them. The first component has a leading portion (3) which enters the second component (2) in use and is connected to a trailing portion which abuts but does not enter the second component after joining. The penetration length of the leading portion is not less than, preferably substantially equal to, a lateral dimension of at least that part of the trailing section adjacent the second component after joining. In another example, the leading portion of the first component is provided with a plurality of re-entrant cavities.

The invention relates to a fixing element, comprising a concentric front face forming a friction surface for friction welding joining to a planar component fixed against the rotational and axial forces acting on the component by the fixing element and with several radial beads on the front face. The beads are defined in the rotational direction by a front groove let into the friction surface, the beads only having a marginal axial projection relative to the friction surface and are provided with a scraper surface from which the scraped material is pushed into the front groove during the welding process.

The invention relates to a friction welding joint of a plurality of two-dimensional components positioned on top of each other, which are held together by means of a connecting body, which rests on an upper component by means of a collar. The connecting body is configured as a pipe piece, and the upper component is penetrated by the connecting body having a front annular cutting edge by means of rotation and pressure, wherein the connecting body, after cutting through the upper component with the front thereof and receiving the cut-out material of the upper component in the hollow space thereof, together with the lower component forms a friction welding zone created by means of rotation and pressure of the connecting body.

The invention relates to a method for friction welding components (35) during which both components are rotated relative to one another during a heating phase under mutual axial pressing force (F) generated by a pressing force actuator (8a) at the location to be welded when component (3) is at rest and when driven component (5) is rotating. In addition, after the components (3, 5) have been subjected to a sufficient friction heating, the rotating is slowed down and the components, which are stationary with regard to one another, are pressed together with a pressing force that is significantly greater than that during the heating phase. The rotated component (5) is driven by an electric motor (7), which is provided with a controller (19) and whose rotational speed (n), torque (RF), pressing force (F) and advancing depth (S) are measured by the controller. The rotational speed is, according to an axial initial pressing force (F) between both components, set by the controller to an initial rotational speed that causes the contact surfaces of both components to melt, and is maintained until the torque drops as a result of the melting of the contact surfaces of both components, during which the rotational speed is decreased and is reduced to zero. Once the rotational speed is zero, the pressing force is increased to a maximum so that the fixed welding ensues on the contact surfaces of both components.

L'invention concerne un procédé de bouchage, par soudage par friction, d'un trou (2) d'une pièce métallique (1), débouchant sur une surface endroit (1') et une surface envers (1") de la pièce (1), dans lequel une barre métallique (3) est mise en rotation et est introduite dans le trou (2), par son côté endroit, pour y être soudée par friction. Le procédé de l'invention est caractérisé par le fait qu'une pièce de bridage (5), comprenant une cavité (6), est placée du côté envers de la pièce (1) durant l'opération de soudage par friction. Le procédé de l'invention autorise le soudage de matériaux à adoucissement rapide tout en assurant une contention du mélange de soudure.
