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.

Bimetallic static gasket and method of construction thereof

A multi-layered composite gasket () includes three, preferably metallic cores (). A solid center core () is flanked on both sides by bonded paper layers (). Perforated cores () mechanically interlock with each paper layer () through inwardly directed tangs (). Graphite layers () are disposed outside of each perforated core () and are mechanically interlocked thereto by outwardly directed tangs () extending from the perforated cores (). When using the gasket () material for sealing cylinder heads in internal combustion engines, a fire ring () may be affixed with a fire ring holder (). The gasket () can be manufactured by making first and second preform sheets () comprised of one perforated core () sided with one paper layer () and one graphite layer (). The preform sheets () are then bonded to a center core () using a heat activated adhesive. Combining rollers () compress and densify the layers to form the completed material set which can be stored on a coil () or cut into sheets.
