ULTRASONIC DETECTION AND SIZING OF TWO-DIMENSIONAL WELD DEFECTS IN THE LONG-WAVELENGTH LIMIT
A new ultrasonic inspection technique is described for detecting elongated defects in butt-weldments. The technique can be used to detect and size two-dimensional defects which can potentially impair the fitness-for-purpose condition of pipeline girth welds. The defect sizing is accomplished by inverting long-wavelength scattering data obtained with shear-horizontal (SH) waves.
