PHASED ARRAY ULTRASONIC TESTING (PAUT)
Phased Array ultrasonic testing (PAUT) is an advanced method of ultrasonic testing. Phased array ultrasonic method can reveal defects embedded in the material that cannot be easily resolved with conventional ultrasonic testing.
The phased array probe consists an array of number of small ultrasonic transducers each of which can be pulsed individually.
The ultrasonic beam is swept like a search-light through the object being examined, and the data from multiple beams are put together to make a visual image showing a slice through the object.
A required angle of the ultrasonic beam can be obtained by varying the pulsing timing of each element commonly called as electronic beam steering.
The use of multiple probe elements produce a steerable, focused, high-resolution beam.
Compared to conventional ultrasonic testing, Phased Array ultrasonic testing instruments and probes are complex and expensive and requires highly trained, skilled and experienced technicians.
The Phased Array Ultrasonic Testing is highly recommended for critical discontinuities detection, sizing and monitoring in aerospace industry, power general industry, nuclear industry and petrochemical industry.
