Digital ultrasonic flaw detectors are modern age portable and processor-based flaw detectors. They are made up of parts including an ultrasonic transducer, hardware & software for capturing signals and analysing them, a data logging module, and a waveform display for viewing the images and graphs. The returning ultrasonic signals are processed digitally through these instruments for…
Ultrasonic flaw detection equipment uses NDT (non-destructive testing) methods to detect surface and subsurface flaws. As the name suggests it uses high-frequency ultrasonic waves for this purpose. A transducer emits the waves into the test object. The returning waves generate clear echo patterns which are then recorded, displayed in the form of images, and interpreted. Ultrasonic…
Portable ultrasonic flaw detectors are used increasingly across all industries, whether they be manufacturing, infrastructure projects, oil, and gas industry, or transport and aviation. These devices apply non-destructive ultrasonic waves to detect flaws. The flaws if not detected beforehand can result in major damages whether financial, environmental, or loss of life and limb. Flaw detectors are…
There are several uses of ultrasonic flaw detectors in a wide range of industrial applications. Flaw detectors use non-destructive techniques (NDT) that employ ultrasonic waves for the purpose. The devices generate ultrasonic waves which pass through the test subject and reflect after striking the flaws and generate clear echo patterns. These patterns are recorded, displayed, and interpreted.…
The ultrasonic thickness gauge is a portable device for measurement by utilising ultrasonic waves. The ultrasonic waves emitted by the gauge transmit through the measured object from one end to the other, after reaching and striking the material interface, the ultrasonic waves bounce back to the gauge. By accurately measuring the time taken by ultrasonic waves to…
Ultrasonic Testing (UT) means the application of a short and high-frequency ultrasonic pulse to detect flaws in an object or material. There are several non-destructive examination (NDE) ultrasonic techniques. The testing is done by emitting the waves into the material tested. By measuring the volume of these waves returning, the internal flaws and properties of…
What Is Ultrasonic Testing? Ultrasonic testing or in short UT refers to a variety of non-destructive testing (NDT) techniques that use ultrasonic waves to pass through a substance or object. Ultrasonic waves are high-frequency waves that are passed through different substances to find flaws or detecting variations in them. Ultrasonic testing applications can utilize frequencies…
Ultrasound is the sound above the human hearing range having shorter wavelengths. Though ultrasound starts at 20 KHz and above most ultrasonic transducers start from 200 KHz. The ultrasonic transducers are sensors that work by using ultrasonic sound waves. These transducers convert the electrical signals to ultrasonic waves or vibrations which are focused on the intended object.…
In this blog, we will look at the advantages and disadvantages of ultrasonic testing in detail. Ultrasonic testing or UT is a technique of non-destructive testing (NDT) that is based on the propagation of the ultrasonic waves in the material or object being tested. In the most common ultrasonic testing applications, short ultrasonic pulse-waves having…
There are more than one NDT methods. Non-destructive testing or NDT is an analysis and testing-based technique that is used by industry for evaluating the properties of a component, structure, material, or system for welding defects or characteristic differences and discontinuities without causing any damage to its original part. NDT is also called Non-destructive Inspection…
