Abstract
The welding ring described connects two housing parts of an electrical battery with electrode stacks arranged symmetrically relative to the welding seam. The ring is provided with spring tongues pointing radially inward and axially upward and downward which hold the electrode end plates on their end faces against an appropriately shaped bearing point so as to center them and retain them in their axial position. This arrangement makes it easier to weld the housing and prevents welding beads from penetrating into the container. Also, additional retention of the electrode stack is ensured.
