Believe it or not, ut flaw detectors are among the most important nondestructive testing instruments. They are fast, highly accurate and are able to detect defects on materials internally and externally. These are some of the reasons that make them useful in many key industries, for the purpose of checking material quality.
In this article, we will let you know the advantages that ultrasonic flaw detectors have over other kinds of NDT testing, and we will go a step further and give you valuable information on how to choose the best ultrasonic flaw detectors, and our recommendation for the best UFD so far. Read on for all this and more.
I. Advantages of Using Ultrasonic Flaw Detectors
Here are some of the advantages of using ultrasonic flaw detectors.
.
Unlike other flaw detectors that can only identify the presence of defects, ultrasonic flaw detectors can identify and give the estimated size of the specific defect.
Some of the common defects in materials include; corrosion, voids, leaks, sealant disbonds, dents, cracks (surface and subsurface), and defects in weld bonds. Moreover, ultrasonic flaw detectors can be used for both ferrous and non-ferrous materials and can be used for testing very thick components with the same efficiency as thin materials.
Ultrasonic flaw detection uses the principles of straight beam and angle beam inspections to give the size and location of a flaw on the surface or inside of a test material.
Because of this, ultrasonic flaw detectors have found use in a wide range of applications in production and service industries especially where metal and welded structures are used. Examples of these industries are, infrastructure; where it is used to monitor for corrosion in metal structures such as bridges and other metal building parts. In the petroleum and oil industries, ultrasonic flaw detectors are used to check for leaks and wall thickness of pressure vessels, pipes and tanks.
The working principles of the ultrasonic flaw detector, together with the use of the proper transducers for different materials results in the instrument giving fast and accurate results. Most ultrasonic flaw detectors work at a high frequency of up to 15MHz, making them faster and more accurate than other instruments.
Ultrasonic flaw detectors come with inbuilt software that uses the various sizing techniques and flaw detection techniques to give a complete scanning report to the technician. It saves you the time and effort of doing manual calculations.

How to Choose the Best Ultrasonic Flaw Detector?
Ultrasonic flaw detectors are important instruments in checking the integrity of materials and components in various key industries. This monitoring helps in maintenance and repair work of any materials with defects helping you save money and prevent accidents that may be caused by flawed materials.
There are some key features that you need to look out for when choosing the best ultrasonic flaw detector for your business and applications as discussed below.
There are several methods for defect characterization and sizing for ultrasonic flaw detection. They include distance amplitude correction (DAC), Distance gain sizing (DGS/AVG), and Time varied gain (TVG).
A good ultrasonic flaw detector uses a combination of these methods for detecting and sizing defects accurately. When looking for the best ultrasonic flaw detector, confirm the kind of flaw sizing methods the instrument uses from its specifications information.
What sets ultrasonic flaw detectors ahead of other NDT instruments is their efficient operational features. No matter the kind of material or component you are testing, an ultrasonic flaw detector works fast to give you real time results for faster important decision making. An instrument’s frequency is what determines the speed of its output. Therefore, make sure to check specifications carefully before purchasing.
As mentioned above, one of the advantages of an ultrasonic flaw detector is that it uses advanced software for data collection, presentation and reporting.
There are different kinds of software for different ultrasonic flaw detector models. Ensure you choose a model that has a software that does all the analysis and report creation for you. That way you avoid human errors during measurements.
The kind of display of an instrument matters a lot, in fact, it is what determines the overall accuracy of your work. A high resolution display gives you clear images for you to make decisions accurately to avoid costly repairs or accidents in future.
Always choose an instrument with a clear and sizeable display, which can work well both indoors and outdoors settings. That way you will not strain your eyes or do guess work while doing material quality checks.
It is important to know the price range of the ultrasonic flaw detector you choose to confirm that it fits within your budget. It is possible to get a cost effective detector that is good quality and highly accurate, so don’t be worried if your budget is small.
Depending on the kind of work that you do, check on the instrument design to ensure it is rugged and robust enough for tough jobs, while still user friendly and light enough to move around with during scanning. A cordless ultrasonic flaw detector, for example, is your best pick if your work involves a lot of movement.
