Abstract

A static gasket and method of construction thereof is provided. The gasket includes a functional layer constructed of one type of metal having an opening bounded by an inner periphery an outer periphery. The gasket further includes a carrier layer constructed of a different metal than the functional layer. The carrier layer has an opening bounded by an inner periphery configured to receive the outer periphery of the functional layer in a line-to-line or loose fit. The functional layer is configured in substantially coplanar relation with the carrier layer with a first portion of the outer periphery of the functional layer being welded to a radially aligned first portion of the inner periphery of the carrier layer. A second portion of the outer periphery of the functional layer remains detached from a radially aligned second portion of the inner periphery of the carrier layer.
