Phased Array Ultrasonic TestingPAUT

PAUT is an advanced method of ultrasonic testing that has applications in medical imaging and industrial testing. When applied to metals the PAUT image shows a slice view that may reveal defects hidden inside a structure or weld. Phased array uses an array of elements, all individually wired, pulsed and time shifted. A typical user friendly computerized setup calculates the time delays from operator input, or uses a predefined file: test angle, focal distance, scan pattern and so forth. The technique also provides a combination of various scans in the same equipment set-up. B-Scan is a side view, Scan is a top view and the S-Scan is a cross-sectional view.
