Abstract: A control arm includes a first component having a first perimeter, a second component having a second perimeter, wherein the first and second components are cast and wherein the first and second components are welded at the first and second perimeters. A control arm includes an upper component, a lower component, and a vertical component disposed between the upper and lower components, wherein the vertical component is welded to the upper and lower components. A method of fabricating a control arm includes casting a first component having a first perimeter and a seat disposed on the first perimeter, casting a second component having a base and a wall, and coupling the first component to the second component, wherein the wall is welded to the seat.

Abstract: An embodiment in accordance with the present invention provides a method for the production of castings with incorporated tubes, where the castings are from cast metal and where the tubes are cast-in with a superheated molten metal. Multiple tubes or a plurality of designs may be incorporated into the invention. The present invention also provides a method for cooling the interior of a cast product before, during, and after the product is cast.
