Phased Array Ultrasonic Testing of Dissimilar Metal Welds using Geometric based Referencing Delay Law Technique 87 -- PART III COMPETITION BETWEENPhased array ultrasonic testing (PAUT) techniques are widely used for the non destructive testing (NDT) of austenitic welds to find defects like cracks. However, the propagation of ultrasound waves through the austenitic material is intricate due to its inhomogeneous and anisotropic nature. Such a characteristic leads beam path distorted which causes the signal to be misinterpreted. By employing a reference block which was cutout from the mockup of
