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 ...
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.
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]
By applying a small load, the material will deform. A nonuniform material quality will generate a nonuniform movement of the surface of the test object. A new shearing image is recorded at the loaded state and is compared with the sheared image before load. If a flaw is present, it will be seen. [4]
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 ...
Jeremy Dunn (Laser Technology Inc.) developed a police lidar device in 1989, [3] and in 2004 10% of U.S. sales of traffic enforcement devices were lidar rising to 30% in 2006, [1] given the advantages of lidar it appears likely that the majority of current sales are lidar, although sophisticated radar units are still being sold.
Flaws (such as fabrication cracks, fatigue cracks, creep cracks and corrosion damage) can arise during the manufacture and use of metallic components. For safety-critical items such as aircraft , pipelines and pressure vessels , the failure of a single component due to the presence of a flaw can threaten human life, as well as having severe ...
