ABSTRACT:
In one aspect the invention provides a friction welded component and a method of manufacture for such a component, comprising friction welding a reinforcement element (10) at an end cross-section thereof to a surface of a thin walled member (12) with an interlayer member (14) interposed between the reinforcement element and the surface of the thin walled member. The thin walled member and/or the interlayer are preferably of the same or similar material and the thickness of the thin walled member is preferably less than or equal to 6 mm and more preferably in the range 0.5 to 2 mm with the diameter of the reinforcement element being greater than 10 times the thickness of the thin walled member. The invention finds particular application in the fabrication of bosses to gas turbine aero-engine casings and fabricated nozzle components, for example.
