Ultrasonic Scanner: The Ultimate Guide

Would you rather remain confused about how ultrasonic scanners work or read this guide and become better informed?

Ultrasonic scanners have become dear to many manufacturers and quality inspection outfits due to their possession of some advantageous attributes: their accuracy of scanned data, portability, and ease of use. However, a few individuals are still confused about how UT scanners work and how they can take full advantage of their functions to inspect things like weld quality and corrosion mapping.

This guide gives a complete rundown of ultrasonic scanners, including how they work, their benefits, their application, and the types available in the market today.

So, without further ado, let’s launch in.

I. What is an Ultrasonic Scanner?

Ultrasonic scanners, also known as UT scanners, are non-destructive testing devices that use high-frequency sound waves with short wavelengths to identify defective properties in a given material or component. Generally, they rely on the velocity of travel of sound waves through a given material and the time it takes to receive an echo after the sound waves hit the backend of the material. Nonetheless, there is still the need to utilize another additional tool like the graphical display screen to analyze the scanned data accurately. 

In addition to that, UT scanners can operate both manually and as an integrated part of an automatic quality assessment system used for various inspections, including corrosion mapping, welding inspection, and thickness mapping.

II. How to use UT Scanner?

For starters, UT scanners are based on ultrasonic sound waves projection and reception to monitor and identify flaws in material components. This understanding is the first stage in using UT scanners. However, the whole process involves three steps, including inserting the UT scanner probe into a frame and placing the setup on the material sample under examination. Secondly is getting the input setting for the scanner, and finally, is the actual scanning process involving moving the scanner over the concerned area.   

Typically, the scanner can contact the test sample using a couplant like gel, water, or oil to increase the effectiveness of the procedure, as ultrasonic waves can be lost when couplants are not used. In any case, couplants might be unnecessary when using an electromagnetic acoustic transducer (EMAT). Still, the transducer often receives ultrasound signals by either attenuation or reflection. The transducer acts as both the sender and receiver of ultrasonic signals for the reflection or pulse-echo case. The diagnostic display shows the extent of the defect within the sample material.

On the other hand, the attenuation mode uses separate transducers to send and receive ultrasonic signals used to determine the extent of damage from the time travel of the wave to and from the backend wall of the test sample.

III. What are UT Scanners Used for?

The use of UT scanners is very effective for different applications in various industries. In most cases, these applications are centered around checking for flaws and assessing the quality of component materials, especially where access to internal parts is somewhat tricky. Nonetheless, UT scanners give accurate results with access to just a single side of the material or component.

These applications include 

  • Weld inspections – This involves the assessment of welding quality to identify defects such as discontinuities, cracks, and porosity which often affects the integrity of the welds.
  • Corrosion or thickness mapping – This involves ascertaining the level of corrosion experienced by a metallic material after it’s been exposed to moisture for a period. It also confirms if the thickness of the metal can achieve its initial design objective. 
  • Surface inspection – This involves assessing the presence of anomalies on the surface of component materials, including surface cracks and delamination. 
  • Tubing inspection – Tubes have unique inspection challenges as internal access is usually difficult for tubing. However, a UT scan is very effective in identifying these flaws.
  • Composite material inspection – Inspecting composite materials, including fiber composites, involves assessing the individual components that make up the composites and the identification of defects.

IV. Why should a Scanner be Used for NDT Inspections?

Most industrial manufacturers have different reasons for adopting UT scanners as their preferred non-destructive testing (NDT) method. However, most reasons you’ll hear center around the numerous benefits that individuals, including quality assessment officers, garner from using UT scanners.

One of the essential benefits is its ease of use. Ultrasonic scanners are often very easy to use, and almost anybody with minimal training can handle an ultrasonic scanner for an NDT inspection. Coupled with the ease of use is portability which allows for easy transportation on the field for NDT inspections. 

Another important reason is the speed with which you can get a result of an NDT inspection when using an ultrasonic scanner. Remarkably, the speed is almost instantaneous for UT scanners as compared to other forms of inspection methods. 

Perhaps the most important reason is the high accuracy and precision of the result of ultrasonic scanners when it is used to conduct NDT inspection. It is especially effective in identifying internal flaws or hidden defects that are often difficult for other methods to identify because of limited access. 

The wide range of applications is yet another reason why ultrasonic should be used for NDT inspections. It can accurately meet inspection objectives for numerous applications, including welding, thickness, and corrosion inspection. 

V. What Types of UT Scanner are there? 

UT scanners are available in various types and brands. Still, they are generally categorized based on application and industry and sometimes on the automation required for the scanning work. 

For application-based scanners, they are often manufactured to suit a specific application and its requirements for ease of use and accurate result. For instance, scanners designed for welding applications often have frames with enough clearance for the probe to access the welded area. Also, they have clamps that can grip the material’s surface if they need to make a rotational movement, like in the case of pipes and tubes. They can also have a single probe or dual probes as well as a phased array arrangement. Some popular application-based scanners are weld, corrosion mapping, thickness mapping, and tanks scanners.

Industry-based UT scanners’ requirements revolve around specific industry requirements, and they are designed to suit the challenges experienced by scanning components within the industry. Take the oil and gas industry, for example, where they use a lot of pipes buried in the ground to transport their produce. Scanners that will be suitable for this industry will give an accurate result with limited access. 

Additionally, they must be very portable as a lot of the scanning work will be done in the field in remote locations. Finally, they have automation tendencies and often use phased array probes arrangement to increase the accuracy of scanned data. Some popular industry-based include handheld scanners, near drum scanners, automatic tracking scanners, and crawler scanners.

Conclusion

So, there you have it. Ultrasonic scanners use high-frequency waves to detect flaws in a given material or component. But why are they often very effective for various applications like welding, corrosion mapping, and thickness mapping? 

It is also vital to note that selecting the suitable UT scanner starts with identifying your specific objective and the requirements for achieving your objective. Also, getting a supplier with a track record of ultrasonic testing equipment delivery can go a long way to help you achieve your quality assessment goals.
