Ultrasonic testing is a method used for determining the thickness of a structure with the help of sound waves. These sound waves are of high frequency, and this method is a reliable non-destructive method used in the power generation industry. There is no need to cut the test piece or use any chemical that might deteriorate it. The sound waves travel through the surface of even sturdy metals and help determine the thickness.   How does Ultrasonic Testing work? High-frequency sound waves that are way beyond the limit of the human ear get induced in this non-destructive testing technique. The test is performed under the supervision of an expert only. They can do the setup with proper requirement standards. Devices are used to induce the sound waves into the material in question. These sound waves can penetrate through any surface except for paper or wooden products. After passing through the surface, the sound wave is reflected when hitting the boundary and is returned to the so

An ultrasonic thickness gaugeis one of the most popular industrial non-destructive testing (NDT) tools. It measuresthe thickness of material when only one side is accessible. It functions non-destructively, using ultrasonic waves to detect changes in the material. Before getting in the detail ofdifferent ways to use an ultrasonic thickness gauge , it is necessary to understand how these gauges work. A dual-element transducer consists of two crystals. In this gauge, the ultrasonic waves sent from one crystal create a 'V' pattern by hitting the material's back wall and reaching the other crystal. The gauge measures the time taken for the ultrasonic pulse to travel to and forth. Taking variables like the speed of the pulse, material, and any potential acoustic barriers, it calculates the wall's thickness. A single element transducer uses only one crystal to send and receive the pulse. Here are the three ways to use an ultrasonic thickness gauge:         i    For coat
