Publication number: 20070186655Abstract: A method for non-destructively inspecting a composite structure with a single ultrasonic transducer includes determining a calibration amplitude of ultrasonic transmissions emitted by the single ultrasonic transducer to a reflector in a fluid-filled immersion tank and received back at the single ultrasonic transducer. The method also includes inserting the composite structure into the fluid-filled immersion tank between the reflector and the single ultrasonic transducer. In addition, the method includes scanning the composite structure with the single ultrasonic transducer to measure ultrasonic amplitudes for sound waves traveling through the composite structure, reflecting off the reflector plate and then traveling back through the structure to the single ultrasonic transducer.Type: ApplicationFiled: February 15, 2006Publication date: August 16, 2007Inventors: Francis Reed, Thomas Batzinger

Publication number: 20060058974Abstract: A digital radiography imaging system for acquiring digital images of an object, and a method for transforming digital images into an absolute thickness map characterizing the object under inspection. The system includes a radiation source for directing radiation through a desired region of the object, and a radiation detector having a plurality of sensing elements for detecting radiation passing through the object. Numerical data generated from each sensing element is calibrated, for example by correcting for variations in radiation paths between the source and detector, by correcting for variations in the spatial frequency response (MTF) of the detector, by correcting for variations in the geometric profile of the object under inspection, and by correcting for material contained in and/or around the object. The calibrated data is processed in order to generate and display an absolute thickness map of the object.Type: ApplicationFiled: April 18, 2005Publication date: March 16, 2006Applicant: GE Betz, Inc.Inventors: Brian Lasiuk, Thomas Batzinger, Manoharan Venugopal, Elizabeth Dixon, Michael Hopple, Nityanand Gopalika, Sivaramanivas Ramaswamy, Debasish Mishra, Rajashekar Venkatachalam, Vamshi Reddy Kommareddy

Publication number: 20050057247Abstract: An omnidirectional eddy current probe includes a number of sense coils arranged in a stack having a principal axis. At least two of the sense coils are rotationally skewed about the principal axis relative to one another. The sense coils are operatively connected to each other and a drive coil is also positioned in the stack. An impulse through the drive coil induces a magnetic influx through a conducting material specimen having a surface, thereby generating eddy currents on the surface. Secondary magnetic field generated from the eddy currents produces corresponding signals in the sense coils, and the signals are then analyzed for the possibility of surface flaw in the conducting material.Type: ApplicationFiled: September 12, 2003Publication date: March 17, 2005Inventors: Thomas Batzinger, Shridhar Nath, Curtis Rose

Publication number: 20050041775Abstract: A system and method for high-speed radiographic inspection of fluid transport vessels in which a radiation source and a radiation detector are positioned on opposite sides of the outside surface of the vessel. A positioning system is provided for moving and locating the radiation source and radiation detector longitudinally with respect to the vessel and for moving the radiation source and radiation detector circumferentially with respect to the vessel. In operation, the positioning system causes the radiation source and radiation detector to spiral along the vessel in a coordinated manner while the radiation source illuminates an adjacent region of the vessel with radiation. The radiation is converted into corresponding electrical signals used to generate images of objects in the radiation path. Finally, an operator inspects the images for defects.Type: ApplicationFiled: August 22, 2003Publication date: February 24, 2005Inventors: Thomas Batzinger, Brian Lasiuk, Peter Allison, Gregory Mohr, August Matula
