The cylinder head gasket, for an internal combustion motor, has a metal base plate with at least one opening for the cylinder combustion chamber, and a metal ring around the opening which is welded to the base plate. The gap (S) between the centers of adjacent weld points (6) is larger than the dia.(D) of the weld points on the surface of the laid ring (4). The dia. of the weld points is ? 1 mm, and the welds are formed by a laser. The overlaid rings (4) have a thickness of 50-120 mu m.
