ABSTRACT:
This invention relates to a coupling involving two components butting one on the other under preload via at least one mating surface, where a coupling sleeve overlapping the two components in the area of the mating surface lodges against the first component via an abutment and the preload is transmitted to the second component via a welded joint. In this manner the components are joined together in a heat-resistant, inseparable, small-bulk and low-weight connection that can be gas-tight if the mating surface and the components are designed accordingly and that is feasible also when the components are made of materials that do not permit brazing or welding them together or cold or hot forming.
