Abstract
A method for fastening by brazing (hard-soldering) the blades of a rotor for a hydrodynamic torque converter or the like, in which the blades are fastened with respect to an inner shell by means of lugs which are extended through corresponding slots in the inner shell and are thereafter bent over; in the assembly, the blades are fixed in the given position in an outer shell by one circumferential clamping band each whereafter the inner shell is assembled by extending the lugs through the slots thereof and the lugs are thereafter bent over; a wire ring of soldering or brazing material is then applied at least within the joint area of the outer clamping band with the outer shell and the assembly is then heated, preferably in a protective gas atmosphere to a temperature above the melting temperature of the soldering or brazing material; after the soldering or brazing material has run into the gaps and cracks the assembly is then cooled.
