ABSTRACT:
Cylinder head gasket with a gasket plate having several sheet-metal layers and at least one combustion chamber aperture, wherein a first outer sheet-metal layer is provided with an annular bead which surrounds the combustion chamber aperture, projects in the direction towards an adjacent, second sheet-metal layer and abuts against the latter, and wherein to limit the deformation of the bead a metal spacer ring is attached by welding to one of the two layers radially adjacent to the bead, the spacer ring facing the other layer and surrounding the combustion chamber aperture; in order to make a simple optical examination of the quality of the welding join possible, the spacer ring is attached in a gas-tight manner to the layer supporting it by a continuous, annular laser welding seam closed upon itself and uniform except for an area of overlap, wherein the seam is doubled in the area of overlap.
