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.

Dependent claims

A static gasket, comprising:

at least one metal functional layer constructed of one type of metal, each functional layer having an opening bounded by an inner periphery configured to register circumferentially with an opening to be sealed and having an outer periphery;
at least one metal carrier layer constructed of a different metal than said at least one functional layer, each carrier layer having an opening bounded by an inner periphery configured to receive said outer periphery of said at least one functional layer in a line-to-line or loose fit;
and
said at least one functional layer being configured in substantially coplanar relation with said at least one carrier layer with a first portion of said outer periphery of said at least one functional layer being welded to a radially aligned first portion of said inner periphery of said at least one carrier layer at a butt weld joint with a second portion of said outer periphery of said at least one functional layer remaining detached from a radially aligned second portion of said inner periphery of said at least one carrier layer.
