Phased array ultrasonic testing (PAUT)

Phased array

Phased array ultrasonic testing (PAUT) is a versatile tool which can potentially be employed in almost any test where conventional ultrasonic flaw detectors have traditionally been used.

Phased array uses a probe made up of multiple small elements. The elements are controlled by software to transmit and received in a pre-determined sequence to scan the test item. 

Weld inspection and crack detection are the most common applications and these tests are done across a wide range of industries including aerospace, power generation, petro chemical, metal billet, and tubular goods suppliers, pipeline construction and maintenance. 

Phased array technology offers the following benefits:
