PAUT was established in advanced method of Ultrasonic Non-Destructive Testing, which can be used in any application environment where traditional ultrasonic flaw detectors can be used. Phased Array techniques allow the user to control parameters such as beam angle and focal distance to create an image of the test part, enhancing defect detection and speed of testing. Typical applications include Weld Inspection, Crack Detection, Corrosion Mapping, Aerospace and Composite Testing.
Phased array ultrasonic systems utilise multi-element probes, which are individually excited under computer control. By exciting each element in a controlled manner, a focused beam of ultrasound can be generated. Software enables the beam to be steered. Two and three dimensional views can be generated showing the sizes and locations of any flaws detected.
