Ultrasonic Flaw Detection

Product Description

Ultrasonic Testing makes use of short Ultrasonic pulse-waves. Comforted with center frequencies ranging from 0.1 MHz-15 MHz that can rise up to 50 MHz on certain occasions, these waves are quiet efficient. Incorporated into specimen to categorize materials,pulse-waves detect internal defects. Ultrasonic thickness measurement test determines the thickness of the test material like monitor paperwork,. Ultrasonic testing is performed on various metals and alloys such as steel. However, owing to its less resolution, it is perfect for thickness test of concrete, wood and composites. NDT method and this non destructive process is also used in multiple transportation related industries like aerospace, automotive, etc. Transducer performs on both the sending and the receiving of the pulsed waves in pulse echo mode. In this specific process, when the sound comes in the contact of any object or wall, it is reflected back. Results are produced in form of a signal by diagnostic machine along with an amplitude which denotes the reflection intensity and the distance, representing the reflection arrival time.
