Abstract
The invention refers to a gasket (1), the gasket having at least one metal layer (3) and at least one metal ring (5) welded thereto, the metal layer (3) having at least one through-hole (4) and the metal ring (5) being arranged around the through-hole, (4). The metal layer (3) and the metal ring (5) are welded to each other along a welding bead (7) which keeps the metal layer (3) and the metal ring (5) in a spaced apart relationship to one another. The gasket (1) has welding joints which are stable for a long time, and thus a high sealing capacity.
