    Abstract: Disclosed is a beam overlap verification system and method for phased array ultrasonic inspection. A scan plan for the ultrasonic inspection defines a suitable probe, wedge and calibration block having machined defects for the geometry to be inspected, and makes a beam definition which defines a set of ultrasonic beams emitted by the phased array. An intersection amplitude unit records the response amplitudes from each defect at predetermined intersection points of adjacent beam pairs as the probe and wedge are manually scanned across the calibration block. An overlap verification module determines the ?6 dB overlap of all adjacent beam pairs which are relevant to the geometry to be inspected, and verifies that the beam overlap conforms to the required coverage according to the ASME or other relevant codes. In this way, coverage is experimentally verified during calibration prior to inspection of a known geometry, such as a weld.
