The invention concerns the connecting of components by friction welding, in particular for connecting pipes in situ when sinking well drill holes and/or completing bores, for example underground bores. The amounts of heat necessary for the welding process are generated by a friction element in a manner known per se, and the ends of the components to be connected are joined in an upsetting process when a weldable plasticized state has been attained. According to the invention, the friction element is a simple friction disc whose material is completely used up during the friction process in the region of the friction surfaces until the components to be connected contact each other. The resultant friction and upsetting burr is removed by utilizing the rotational energy of the friction element. Whilst reducing the level of complexity in terms of plant required, the invention permits the use of friction elements which do not have to be adapted to the exact dimensions of the components to be connected. The connection point has a simple weld seam which essentially consists of the basic materials of the components to be connected.

L'invention concerne l'assemblage d'éléments constitutifs par soudage par friction, notamment pour assembler des tuyaux sur place, lors de l'exécution de forages et/ou dans le cadre de la complétion de forages, par exemple des filons caverneux. Les volumes de chaleur requis pour le processus de soudage sont produits de manière connue en soi avec un élément de friction et les extrémités des éléments constitutifs à assembler sont réunies dans le cadre d'une opération de refoulement, une fois qu'elles ont atteint un état de ramollissement apte au soudage. Selon l'invention, l'élément de friction est un simple disque de friction dont le matériau est entièrement usé pendant le processus de friction, dans la zone des surfaces de frottement, jusqu'à ce qu'il y ait contact avec les éléments constitutifs à assembler et l'arête formée sous l'effet du frottement et du refoulement est nivelée à l'aide de l'énergie de rotation de l'élément de friction. La diminution de la complexité que l'invention entraîne côté installation permet l'utilisation d'éléments de friction qui ne doivent pas nécessairement correspondre aux dimensions exactes des éléments constitutifs à assembler. Le point d'assemblage ne comporte qu'un seul cordon de soudure composé essentiellement des matériaux de base des éléments constitutifs à assembler.
