Patent number: 7992416Abstract: Ultrasonic peening treatment is desirable where an application of a compressive stress is helpful to reduce the incidence of crack formation on highly stressed parts. Ultrasonic peening treatment can be performed in field applications without requiring a rotor to be removed from the machine. The system includes an acoustic element that excites peening media within a peen chamber. A frame is attachable to an assembled turbine rotor component and includes support structure engageable with the acoustic element. The frame is cooperable with a chamber tooling that defines and encloses the peen chamber together with the turbine rotor component.Type: GrantFiled: May 12, 2006Date of Patent: August 9, 2011Assignee: General Electric CompanyInventors: Raymond Joseph Stonitsch, Diane Marie Beagle, Jean-Michel Duchazeaubeneix, Patrick Cheppe, Philippe Jacob, Vincent Desfontaine

Publication number: 20100147047Abstract: A method of making undersea steel pipes, by assembling unit pipe elements together end-to-end by welding, the steel or metal alloy weld beads of said welds being disposed on the outside of the pipe, wherein localized peening is performed on the inside of the pipe to increase the compression of the steel or metal in the vicinity of the welds and over the adjacent peripheral inside surface of the pipe on either side of the weld so as to create a swath of surface that has been peened over a limited distance L in the axial longitudinal direction of said pipe. The peening is preferably performed using a wheeled carriage fitted with a peening tool.Type: ApplicationFiled: April 9, 2008Publication date: June 17, 2010Applicant: SAIPEM S.A.Inventors: Eric Kerdiles, Jean-Michel Duchazeaubeneix, Philippe Jacob, Patrick Cheppe
