SIUI develops and manufactures a variety of ultrasound imaging systems and accessories for both human and veterinary use, and NDT equipment including phased-array ultrasonic flaw detector, [3] conventional flaw detector, [4] thickness gauge, probes [5] and accessories. The company is currently organized into three product category divisions ...
James F. McNulty (U.S. radio engineer) of Automation Industries, Inc., then, in El Segundo, California, an early improver of the many foibles and limits of this and other nondestructive testing methods, teaches in further detail on ultrasonic testing in his U.S. Patent 3,260,105 (application filed December 21, 1962, granted July 12, 1966 ...
The dead zone is approximately 5 mm and there is no flaw detection in this zone. Calibration blocks with side drilled holes as shown in Reference [4] and ISO 10863 used to validate the "dead zone" and sizing accuracy.
Traditionally, determining defects, voids and cracks within an object would require destructive testing. CT scanning can detect internal features and flaws displaying this information in 3D without destroying the part. Industrial CT scanning (3D X-ray) is used to detect flaws inside a part such as porosity, [7] an inclusion, or a crack. [8]
Brown, although relatively young at twenty-three, had previously worked on an automatic flaw detector for testing of industrial products. [5] It was while working in the Western Infirmary installing a bulb in an operating theatre that Brown found out that Donald was experimenting with the flaw detector. [ 6 ]
Fault detection, isolation, and recovery (FDIR) is a subfield of control engineering which concerns itself with monitoring a system, identifying when a fault has occurred, and pinpointing the type of fault and its location.
The fluorescent penetrant is applied to the surface and allowed time to seep into flaws or defects in the material. The process of waiting for the penetrant to seep into flaws is called dwell time. Dwell time varies by material, the size of the indications that are intended to be identified and requirements / standards but is generally less ...
For detectors of such a size, gamma rays may Compton scatter out of the detector's volume before they deposit their entire energy. In this case, the energy reading by the data acquisition system will come up short: the detector records an energy which is only a fraction of the energy of the incident gamma ray.
