Ultrasonic testing (UT), which falls under the non-destructive testing (NDT) technique, uses high-frequency ultrasonic sound waves. These transmit into materials for detecting the internal flaws. We do Ultrasonic testing on materials like plastics, metals, ceramics and composites. Most ultrasonic testing machines use short pulse waves having a frequency range of 0.1-15 MHz. You can increase this range to 50 MHz. One common application of this technique is to evaluate the thickness of an object. The best part about the UT method is that there are no health hazards associated with it.

Flaw Detector

Ultrasonic Flaw Detector is the most common and the oldest method among all other industrial applications. In this technique, there is a reflection of sound waves of high frequency through flaws. This process results in a generation of clear echo patterns, whose recording happens on portable instruments. 

Phased Array

Phased Array ultrasonic testing technique uses specialized multi-element “array” transducers. The method pulses those elements separately, known as “phasing”.It further leads to scanning. Phased Array ultrasonic testing is helpful for weld and corrosion inspections as well as flaw detections.

Thickness Gauging

An ultrasonic thickness gauging system measures the thickness of a component by checking the time it takes for a sound pulse that a small probe has generated called an ultrasonic transducer to travel through a test piece and reflect from the inside surface or far wall.

Advanced Thickness Gauging

Advanced thickness gauging system comes in various ranges like the 45gm, which consists of standard measurement features and software options. It is widely used in engineering and manufacturing sectors to check the thickness and density of materials. 

Health Assessment

For many decades, ultrasonic techniques prove beneficial in the medical sector. The usage increases as it has become the most preferred option for both routine diagnostic imaging and medical research. The application is possible due to the absence of ionizing radiation.
