| Testing Method | Primary Capability | Typical Inspection Use / Defects | Related Equipment |
|---|---|---|---|
| Ultrasonic Pulse-Echo (UPE) | Under single-end access conditions, internal reflection signals are captured using transmit/receive transducer arrays, and B-scan or 3D tomographic images are reconstructed using algorithms such as SAFT. | Holes/voids, delamination, cracks, voids behind reinforcing bars, grouting defects in prestressing ducts, tunnel lining thickness; suitable for bridge decks, tunnel linings, foundation slabs, and other structures accessible from only one side | Explore UPE Equipment → |
| Ultrasonic Pulse Velocity Test (UPVT) | By measuring the propagation time (µs) of ultrasonic waves through concrete and calculating the wave velocity (m/s), it is possible to assess the concrete’s modulus of elasticity, density, and uniformity, enabling rapid surveys of large-scale structures. | Evaluation of concrete uniformity; strength estimation (requires establishing a wave velocity–strength correlation curve); assessment of porosity and crack severity; monitoring of structural aging. In transmission mode, the extent of voids, honeycombing, and segregation can be determined. | Explore UPVT Equipment → |
| Phased Array Ultrasonic Testing (PAUT) | Uses multiple transducer elements with electronically controlled beam steering and focusing for multi-angle inspection. Supports encoded scanning and digital imaging, including sectorial scans and other views depending on the system. | Weld inspection, including complex and thick-walled welds; cracks, lack of fusion, incomplete penetration, inclusions and laminations; corrosion mapping and inspection of selected composite materials | Explore PAUT Equipment → |
| Conventional Ultrasonic Testing (UT) | Typically uses single-element contact or immersion probes in pulse-echo mode. A-scan signals support flaw localization, calibrated indication evaluation and thickness measurement | Inspection of welds, forgings, castings, plates, bars, pipes and pressure vessels; detection of cracks, inclusions, laminations and other internal discontinuities. Corrosion thickness measurement is also possible with suitable equipment and procedures | Explore Conventional UT Equipment → |
| Electromagnetic Acoustic Transducer (EMAT) | Generates and receives ultrasonic waves through electromagnetic interaction in electrically conductive materials, generally without couplant. Depending on the configuration, it can inspect hot, moving or rough-surfaced components and generate selected shear, Lamb or guided-wave modes | EMAT enables non-contact ultrasonic testing of conductive metals without couplant, even on hot, moving, rough, or coated surfaces. Typical applications include high-temperature pipe thickness monitoring, pipeline corrosion screening, hot-rolled steel inspection, surface and near-surface defect detection, and multi-parameter measurement. | Explore EMAT Testing Equipment → |

FAQs About Ultrasonic Testing Equipment
Answers to common questions about equipment selection, testing methods and applications.
1. What is the main difference between UPV and Ultrasonic Tomography?
UPV (Ultrasonic Pulse Velocity) typically requires two opposite sides to measure transit time for average quality assessment. Ultrasonic Tomography uses a matrix array transducer from a single side to reconstruct high-resolution 3D images of internal defects, making it ideal for thick or single-side accessible concrete.
