Abstract
The invention relates to a method for the production of a ball joint, in which a cover is electrically welded to a housing, the cover or the housing having at least one spacer which keeps the cover at an excessively great distance from the housing before welding, and in which then the current flowing during welding is controlled or regulated in such a way that the at least one spacer melts by a predetermined amount so that the cover is mounted in a prestressed manner on the housing. The invention further relates to a ball joint with a housing, a link pin, a bearing box and a cover which braces the bearing box in the housing, the cover being provided with at least one spacer which is welded electrically to the housing so that its height has reduced to a predetermined extent.
