Ultrasonic testing has taken a technological step forward with phased-array ultrasonic testing (PAUT). This more accurate and more sophisticated system is being used to certify material to SIM-16, a test specification for new aero-engine designs.
The aerospace industry’s first use of a phased-array ultrasonic testing (PAUT) system was recently installed and is being qualified at West Penn Testing Group’s (WPT) New Kensington, Pa., facility. Aero-engine manufacturers are completing their specifications in order to begin taking advantage of PAUT for nondestructive evaluation of titanium forging stock. To date, WPT’s system has run trials on 5-, 6-, and 10-inch billets earmarked for the forging of flight-critical components such as rotor disks and hubs.
