Abstract

The present invention provides dual-layer to flange weld joint for an exhaust manifold assembly. The manifold includes an inner assembly connected to a flange, and an outer shell spaced apart from the inner assembly to allow for an air gap between the shell and the inner assembly. The outer shell further includes a gap between the end portion of the outer shell and the flange. This gap allows a single exterior weld joint to connect the inner assembly and outer shell to the flange.
