Ultrasonic Pulse Velocity
Ultrasonic Pulse Velocity (UPV) investigations are performed to assess the condition of structural members if access to both sides are available.
Sonic Pulse Velocity (SPV) is performed on mass concrete over 10 ft (3 m) thick
The Ultrasonic Pulse Velocity (UPV) systems are designed to identify and map voids, honeycomb, cracks, delaminations, and other damage in concrete, wood, masonry, stone, ceramics, and metal materials. UPV tests are also performed to predict strength of early age concrete. The UPV methodology relies on direct arrival of compressional waves.
The test is performed by positioning the source and receiver on either side of the area in question, then the source sends a compressional wave through the region, and the receiver records the full waveform on the other side. The position of the two transducers can be varied such that direct, semi-direct, and indirect tests can be performed, which aids in mapping out the volume of the defect. Further tests can be performed if the user wishes to generate a 3-D rendering of the volume in question. This is done by testing many different “paths” through the medium and then using a tomographic inversion program (sold as an optional Add-on feature for the UPV-1 Model) to generate a model.
Hands-on training classes are available for all of our Nondestructive Testing Methods at our Wheat Ridge, Colorado (USA) location, which is a suburb located approximately 15 minutes northwest of downtown Denver. Training may be available at your location by one of our agents upon special arrangement.
