The ultrasonic data obtained are shown for an undamaged bolt and bolts with 5- and 50-percent symmetric corrosion, respectively. Based on the time difference between the backwall signal (seen in all three oscilloscope traces at about 7.5 major screen divisions) and the multiple signals all with the same time separation (seen only in the lower oscilloscope trace), the remaining diameter can be calculated.

Recognized as an international leader in developing and applying nondestructive evaluation (NDE) technology for clients in industry and government, Southwest Research Institute (SwRI) engineers employ various inspection methods such as:

  • Cylindrically guided waves

  • Magnetostrictive sensors

Ultrasonics Projects

Successful ultrasonic NDE projects have focused on applications including:

  • Government infrastructure

  • Utility infrastructure

  • Pipelines

  • Nuclear power plants

  • Military aircraft components
