Bimetallic static gasket and method of construction thereof

A method of constructing a static gasket, comprising:

• providing first and second layers of metal constructed of different types of metal from one another;
• forming the first layer into a functional layer having an opening configured to register circumferentially with an opening to be sealed and having an outer periphery;
• forming the second layer into a carrier layer having an opening bounded by an inner periphery configured to receive the outer periphery of the functional layer therein;
• disposing the outer periphery of the functional layer in the opening of the carrier layer such that the functional layer is in substantially coplanar relation with the carrier layer;
• forming at least one through passage in the carrier layer;
• extending a swaging tool into the through passage to plastically deform a first portion of the carrier layer and bias the inner periphery of the first portion of the carrier layer into abutment with a radially aligned portion of the outer periphery of the functional layer while second portions of the carrier layer that are not biased by the swaging tool remain unbiased;
• and
• welding the portion of the inner periphery of the first portion of the carrier layer to the radially aligned portion of the outer periphery of the functional layer.
