Applications of Non – Destructive Testing (NDT) are very broad varying from the medical to heavy industries. Several advanced NDT methods, mainly developed form of the conventional methods, are used to render the technique more flexible and easier to interpret. Ultrasonic Phased Array method can be employed in almost any test, where conventional Ultrasonic Testing (UT) has traditionally been used. The benefits of Phased Array technology over conventional UT come from its ability to use multiple elements to steer, focus and scan beams with a single transducer assembly. In this study, the advantages and limitations of the Phased Array system will be investigated via using several test blocks, prepared from different types of steels, having well-defined artificial defects. The reliability of the Phased Array and conventional Ultrasonic Testing methods will be compared using a statistical approach, the Probability of Detection (PoD).
