Abstract
A friction-weld interface device for improving a structural strength of an assembly includes a first component having a concave tapered surface. The friction-weld interface also includes a second component having a convex tapered surface that is complementary to and is configured to receive the concave tapered surface of the first component. The assembly is formed by friction welding the concave tapered surface to the convex tapered surface. The friction-weld interface device may be used to assemble an air-intake manifold for an internal combustion engine, wherein the air-intake manifold is at least partially joined by the process of friction welding.
