1. A method of forming a heat exchanger, the method comprising:
positioning an insert into at least one fluid passage of a manifold body and at least one fluid passage of a cooling passage section body wherein the positioning the insert further comprises injection of a material into the at least one fluid passage of the cooling passage section body and the at least one fluid passage of the manifold body; and
welding the manifold body and the cooling passage section body about at least a portion of the insert to form a weld joint that fluidly seals the manifold body and the cooling passage section body such that the at least one fluid passage of the cooling passage section body is fluidly coupled to the at least one fluid passage of the manifold body;
wherein the weld-drop-through of the weld joint is substantially even with an interior surface forming the at least one fluid passage of the cooling passage section body and an interior surface of the at least one fluid passage of the manifold body.
