1. A method for producing a composite thickness metal part comprising:
cutting out a base component such that the base component includes a plurality of fingers and a plurality of channels, wherein each of the plurality of channels are disposed between respective ones of the plurality of fingers, the base component having a first thickness;
cutting out a foil sheet, the foil sheet having a second thickness less than the first thickness;
loading the base component and the foil sheet into a fixture;
passing the fixture containing the base component and the foil sheet through an ultrasonic welding machine to join the foil sheet to the base component and form an interim part that includes the foil sheet joined to the base component; and
cutting away preselected sections of the foil sheet from the interim part to produce a final geometry of the composite thickness metal part.
