These transducers are piezoelectric materials that convert one form of energy into another for the purpose of the probe. Sequential driving of the transducers facilitates sector, depth, and linear scanning. It can also be used in cases where conventional ultrasonic inspection (UT) is used. It can be used to inspect wall thickness profiles and weld inspections, as well as heat-affected zone (HAZ) inspections, making it versatile and viable in industries such as manufacturing, construction, petrochemical, and aerospace. Phased-array ultrasonic inspection equipment sweeps the input ultrasonic beam across the test object and therefore detects distortions that
