Phased Array Ultrasonic Testing (PAUT)
PAUT is an advanced Ultrasonic Testing method that has applications in Industrial
Nondestructive Testing. Common applications are to find flaws in manufactured
materials such as welds.
Single-element (non- Phased Array) probes, known technically as monolithic probes,
emit a beam in a fixed direction. To test or interrogate a large volume of material, a
conventional probe must be physically scanned (moved or turned) to sweep the beam
through the area of interest. In contrast, the beam from a phased array probe can be
focused and swept electronically without moving the probe. The beam is controllable
because a phased array probe is made up of multiple small elements, each of which
can be pulsed individually at a computer-calculated timing. The term phased refers to
the timing, and the term array refers to the multiple elements. Phased array
Ultrasonic testing is based on principles of wave physics.
Phased Array Ultrasonic Testing is widely used for Nondestructive Testing (NDT) in
several industrial sectors, such as construction, pipelines and power generation.
Phased Array Ultrasonic Testing method is an advanced NDT method that is used to
detect discontinuities i.e. cracks or flaws and thereby determine component quality.
Due to the possibility to control parameters such as beam angle and focal distance,
this method is very efficient regarding the defect detection and speed of testing. Apart
from detecting flaws in components, Phased Array Ultrasonic Testing can also be
used for wall thickness measurements in conjunction with corrosion testing.
Phased Array Ultrasonic Testing can be used for the following industrial purposes:
Inspection of welds
Thickness measurements
Corrosion Inspection
PAUT Validation/Demonstration Blocks
Rolling stock inspection (wheels and axles)
PAUT & TOFD Standard Calibration Blocks
