Abstract: A method of joining tubes with friction welding includes the steps of aligning end walls of tubes to be welded, introducing an intermediate tube segment between the tubes, and bringing the tube end walls together against opposing end walls of the tube segment to put the end walls under axial compressive stress at a friction ramp-up pressure. The method further includes rotating the intermediate tube segment about a tube segment longitudinal axis in at least one direction, increasing the axial compressive friction stress to a forging pressure in order to heat the end parts of the tube and the intermediate tube segment, and increasing the axial compressive friction stress to a forging pressure, thus joining the tubes and the tube segment. The tube segments have a tube wall made of a material resistant to hydrogen embrittlement.
