Ultrasonic Inspection

Ultrasonic testing is a sensitive, convenient and versatile nondestructive method. It can assess the integrity of a component through different stages of production, fabrication, transportation, and degradation in service.

Ultrasonic testing provides real-time information on porosity, structure, and elastic constants. Macroscopic, hidden, and minute discontinuities, such as voids, cracks, inclusions, and weld defects, can be detected. Accurate measurements of depth/thickness can be performed in thin and thick components alike. This technique is also applicable in corrosion and metallurgical studies, the measurement of elastic moduli, assessment of weld integrity, and many others.

An ultrasonic wave directed into a solid body can be used to measure its material properties as the beam of attenuated ultrasonic energy is transmitted, or flaws as the energy is reflected. A wide variety of ultrasonic methods exist including electromagnetic acoustic transducers, pulse eco straight-beam, angle beam, contact or immersion.

Contact Flaw detection and depth/thickness measurements are performed in-house at Bess MTI and on-site by highly experienced inspectors using state-of-the-art equipment. Our instrumentation consists of the following:

  • 1 DFX-7 Ultrasonic Flaw Detector

  • 2.25 - 10mHz Straight Beam Probes 1/4 - 1”

  • 2.25 – 10mHz Angle Beam Probes 1/4 – 1” with 45˚, 60˚, and 70˚ wedges

  • 5 - 10mHz Dual probes .187”
