Description
The use of phased array ultrasonics for the detection of small defects in welds is described, and illustrated using a series of examples of friction stir welded aluminium alloy plate. Phased arrays use an array of ultrasonic elements pulsed with different delays, to generate an ultrasonic beam, the angle of which can be changed for each pulse, so sweeping the beam through a range of angles. Following calibration runs on embedded defects (EDM notches), tests were made on welds. Faults detected and described include: tight cracks, toe cracks, oblique defects, transverse defects, wormholes, lack of penetration, faying surface defects, and kissing bonds.
