Abstract
A ball joint and a work process for preparing such a ball joint are described, in which the housing is prepared in one piece by a sheet metal shaping process. An edge bead, which is used to close the housing by a cover, is prepared by material deformation on the outer circumference of the housing. A groove for receiving the sealing bellows, which groove is likewise located on the outer circumference of the housing, is formed during the shaping process, so that machining of the housing is not necessary.
