The concept of nondestructive testing (NDT) NDT by ultrasonic pulse velocity or rebound hammer can be effectively used to predict the service life of the structure apart from given in Table 1. The NDT tests were carried out according to ASTM (ASTM C:597). The age of 7, 28 and 90 days for concrete
It generates and displays an ultrasonic waveform that is interpreted by a trained NDT operator, often with the aid of analysis software, to locate and categorize flaws in test pieces. It typically includes an ultrasonic pulser/receiver, hardware and software for signal capture and analysis, a waveform display, and a data logging module. Carbon Steel SA-210 Sound velocity - NDT.netMar 28, 2017 · Re:Carbon Steel SA-210 Sound velocity In Reply to pulkit at 10:35 Mar-23-2017 (Opening). Hello Pulkit, you can use our QSV - ultrasonic velocity gauge to accurately measure material sound velocity based on material thickness.
Dec 12, 2019 · National Inspection Services is a full service Non-destructive Testing (NDT) company. NIS has nine staffed locations with a presence in Louisiana, Texas, Colorado, West Virginia, Pennsylvania, and Ohio. GINDT Ultrasonic TestingUltrasonic Testing. Ultrasonic testing uses the same principle as is used in naval SONAR and fish finders. Ultra-high frequency sound is introduced into the part being inspected and if the sound hits a material with a different acoustic impedance (density and acoustic velocity), some of the sound will reflect back to the sending unit and can be presented on a visual display.
What is Ultrasonic Testing?. Ultrasonic nondestructive testing, also known as ultrasonic NDT or simply UT, is a method of characterizing the thickness or internal structure of a test piece through the use of high frequency sound waves.

Jan 23, 2019 · High frequency sound waves (frequency > 20000 HZ) also known as ultrasonic waves are introduced in a test object through a probe, these waves travel through the material on a predictable path. The waves are reflected at interfaces or other interruptions or discontinuity. Ultrasonic Testing of Ductile Iron Castings to Verify
Apr 01, 2017 · Ultrasonic testing provides a reliable method for measuring sound velocity and, therefore, verifying the nodularity of cast ductile iron parts. Integrating ultrasonic measurement into an automated testing system in a foundry production line enables fast, reliable inspection of 100% of cast production parts. Ultrasonic Testing on Duplex Stainless SteelVelocity = 5780 m/s 50mm Radius 60° 50mm Radius 61.7° ° Duplex material Velocity = 5880 m/s Calibration blocks shall as near as practicable, have the same acoustic properties as the material to be tested (Reference:DNV-OS-F101, para. 204, page- 201) Calibration Block for UT Equipment Sin60° Sin 61.7° 5780 5880 =
