Ultrasonic Phased Array Testing (PAUT Inspection)

A series of ultrasonic testing (UT) probes made up of several microscopic components are used in the advanced non-destructive examination method known as phased array ultrasonic testing, or PAUT. Each one of these small components is pulsed individually with computer-calculated timing.

More complex geometries that are difficult and slower to inspect with single probes can be examined using this technique. PAUT is typically used for weld inspections and crack detection but may be used to inspect almost any material where conventional UT techniques have been applied.

PAUT has a number of benefits over other UT methods. In comparison to other types, PAUT can be performed more quickly, frequently in under a second.

It has a high degree of reproducibility, making it simple to use for repeat scans.

PAUT may generate precise crosssections of a part by sequentially emitting beams at a variety of various angles.

Because it can sweep the beam without moving the probe, it is also particularly helpful in situations where there is less room for mechanical scanning.

For detecting weld faults such as lack of fusion, slag inclusion, porosity, inside diameter/outside diameter, cracks, erosion/corrosion, and inherent discontinuities in forged or casting materials, EIWAA Gulf Rocks offers weld inspection using the phased array technique and the most cutting-edge instruments.
