How is Ultrasonic Inspection Used in Industry?
The industrial reliance on ultrasonic testing (UT) as their primary non-destruction inspection methodology is at its all-time high. This includes aerospace, construction, automotive, oil and gas, power generation, manufacturing, or nuclear industries where UT is utilized as an immediate quality control method. With UT capabilities expanding as a result of newer methods and technologies, the industrial repertoire of UT inspection seems to be ever-increasing.
Here we discuss the industrial usage of UT inspection and its applicability for a wide range of applications.
How Does the Ultrasonic Inspection Method Work?
Most industries make use of UT for the following purposes:
- Quality control
- Routine or emergency inspection
- Preventive maintenance
For either of these purposes, the UT method assists by identifying the existing flaws such as cracks, corrosion, inclusions, porosity, or any other thickness or metallurgical change in the inspection material. UT does so by utilizing transducers that emit high-frequency ultrasonic waves, usually within the range of 0.1 to 15MHz, which pass through the material to diagnose it. The reflected wave received by the receiver is then analyzed to identify and characterize the flaws.
Having this data allows industries to skim out the defective batches and standardize the production process to ensure quality control.
How Different Industries Leverage the Benefits of Ultrasonic Testing
In the upstream, midtown, or downstream oil and gas industry, UT inspection is used for inspection of pipes, storage tanks, welds, and more for preventing material or equipment failure, protecting pipelines and equipment, and ensuring the safety of workers, operation, and environment. Phased array ultrasonic testing (PAUT) and TOFD (Time of Flight Diffraction) make this possible through accuracy, precision, and speed in testing, ensuring quality and productivity.

Ultrasonic testing in manufacturing can broaden to many areas from automotive to heavy-duty manufacturing including pipes and tubes. Each of the manufacturing processes requires careful inspection of components to identify potential flaws. The powerful capabilities of UT instruments, probes, and software has been adopted by manufacturing industries as a quality control tool that analyzes the flaws for potential risks. This is crucial in improving safety, productivity, and in reducing manufacturing downtime.

How is Ultrasonic Inspection Used in Industry: Transportation
Aerospace or aviation industries use ultrasonic testing for ensuring the quality of their wide component ranges, each of which is crucial for proper aircraft functioning. This includes assessing composite materials, complex geometries, and for components like engines, gears, airframe and fuselage, honeycomb structures, and many others. With flexible, portable, and powerful UT solutions, it is easier to perform a volumetric inspection on these complex structures to ensure each part is conforming to industrial standards.

How is Ultrasonic Inspection Used in Industry: Power Generation
Power generation industries, be it nuclear or fossil fuels or wind energy, require many infrastructures with the capability to support high-temperature and pressure requirements. A small flaw can be catastrophic in these industries. Ultrasonic testing can support in-depth flaw detection to identify even the minor flaws in crucial components.
PAUT inspection can assess components like blades, towers, rotor shafts, and gearbox for the potential presence of corrosion, cracking, lack of bonds, etc. in the wind turbines and fossil fuel plants.
