<p>A method and a system that can improve forging shape design to acquire improved ultrasonic inspection coverage are provided, wherein the method provides much greater coverage of ultrasonic inspections than conventional methods and provides more accurate results from the inspections. As a method for modifying a finished machine component forging for ultrasonic inspection, the method comprises: a step(101) of constructing a forging envelope in the form of a right circular cylinder that surrounds a machine component forging; a step(103) of adding material to the forging envelope in the forging direction in such an extent that is equal to about 2 times a wavelength of an ultrasonic inspection device; a step(107) of adding additional material to an inspection surface of the forging envelope equal to the size of a transducer dead zone, if the forging cannot be inspected ultrasonically in the forged direction from two opposing surfaces; and a step(109) of adding additional material to the forging envelope in a direction perpendicular to the forging direction equal to a transducer footprint plus a break edge radius.</p> |
