Abstract
A hydrodynamic machine, and especially a hydrodynamic coupling, for a turbine compound system includes (a) a bladed primary wheel and a bladed secondary wheel which together form an operating space which is filled or can be filled with operating medium, and (b) a housing which encloses the primary wheel and the secondary wheel and which is manufactured from sheet metal. The housing is manufactured from at least two separate sheet metal components which are placed on the primary wheel and/or the secondary wheel, are aligned with each other at a joint abutment location, and are welded together. In the area of the welded joint abutment, a relief which is open toward the joint abutment is provided and which extends along the joint abutment in the surface of the primary wheel and/or the secondary wheel.
