Patent number: 7757364Abstract: To achieve improved ultrasonic testing coverage of a finished machined component, the present invention applies a method for modifying a finished machine component forging for ultrasonic inspection. A forging envelope may be constructed in the shape of a right circular cylinder that surrounds a machine component forging. Then material may be added to the forging envelope in the direction of the forging equal to about 2 times a wavelength of an ultrasonic inspection device. Additional material may then be added to an inspection surface of the forging envelope equal to the dimension of a transducer dead zone, if the forging cannot be inspected ultrasonically from two opposing surfaces in the forged direction. Lastly, material may be added to the forging envelope in a direction perpendicular to the forging direction equal to a transducer footprint plus the break edge radius.Type: GrantFiled: August 9, 2006Date of Patent: July 20, 2010Assignee: General Electric CompanyInventors: Robert V.

Patent number: 7546685Abstract: A process for producing a rotor, the rotor formed thereby, as well as turbines in which such a rotor is installed. The rotor is formed by casting an ingot to have first and second regions formed of different alloys that intermix during casting to define a transition zone therebetween. The ingot is forged to yield a rotor forging that contains axially-aligned first and second alloy regions and a transition zone therebetween. The effects of the transition zone can be mitigated by modeling the transition zone and then off-center machining the forging so that the axis of rotation of the machined monolithic rotor is more centrally located with respect to the transition zone.Type: GrantFiled: March 1, 2005Date of Patent: June 16, 2009Assignee: General Electric CompanyInventors: Swami Ganesh, Robin Carl Schwant, Ling Yang, John Zhiqiang Wang, Francis Alexander Reed, Robert V.
