  • Ultrasonic Flaw Detection
    Of all the applications of industrial ultrasonic testing, flaw detection is the oldest and the most common. Since the 1940s, the laws of physics that govern the propagation of sound waves through solid materials have been used to detect hidden cracks, voids, porosity, and other internal
  • Use of a PC-Based Digitizer in an Ultrasonic Flaw-Detection System
    Use of modern high-speed digitizers in the construction of an ultrasonic flaw detection system is discussed. Topics include the advantages of high sampling speed, high vertical resolution, deep acquisition memory buffers, and fast data transfer speed to the host PC. Issues that arise due
  • Ultrasonic Material Analysis
    Ultrasonic nondestructive testing is a versatile technique that can be applied to a wide variety of material analysis applications. While ultrasonic NDT is perhaps better known in its more common applications for thickness gaging, flaw detection, and acoustic imaging, high frequency sound waves can
  • Miscellaneous Ultrasonic Applications
    a cross-section of the most common uses for ultrasonic thickness gaging, flaw detection, and material analysis. However, there are also many specialized or unusual applications that fall outside the traditional mainstream areas of weld and structural inspection, corrosion survey, and precision
  • An Introduction to Ultrasonic Transducers for Nondestructive Testing
    The high-frequency sound waves used for flaw detection and thickness gaging in ultrasonic nondestructive testing applications are generated and received by small probes called ultrasonic transducers. Transducers are the starting point for any ultrasonic test setup, and they come in a wide variety
  • Application Considerations in Specifying High Frequency Ultrasonic Transducers
    Advances in transducer manufacturing technology and associated instrument electronics have led to the introduction of commercial products that provide the capability for ultrasonic imaging, thickness gaging, flaw detection, and material analysis at test frequencies greater than 50 MHz. In many
