- 5. 5 © - CopyrightBureau Veritas CONVENTIONAL UT Vs PHASED ARRAY To scan the volume of a part we must physically move the probe. Physically movement of the probe not required to cover entire thickness
- 6. 6 © - CopyrightBureau Veritas Phased arrays Concept • A mosaic of transducer elements in which the timing of the elements' excitation can be individually controlled to produce certain desired effects, such as steering the beam axis or focusing the beam. Phased array technology is the ability to modify electronically the acoustic probe characteristics Probe modifications are performed by introducing time shifts to individual elements of an array probe
- 7. 7 © - CopyrightBureau Veritas Phased Array Scanning Types Linear Electronic Scan ► The movement of the acoustic beam is along the axis of the array, without any mechanical movement. ► The beam movement is performed by time multiplexing of the active elements. Arrays are multiplexed using the same focal law.
- 8. 8 © - CopyrightBureau Veritas Phased Array Scanning Types Sectorial Scan ► The ability to scan a complete sector of volume without any probe movement. ► Useful for inspection of complex geometries, or geometries with space restrictions. ► Combines the advantages of a wide beam and/or multiple focused probes in a single phased array probe.

Editor's Notes
- #2 Here it is a clear cut comparison between Conventional UT and LRUT (Long Range Ultrasonic Testing). Where as Conventional UT – In order to cover the Entire length of Material thickness, we need to have the access though out Length. But in LRUT With in a short area of accessibility, we can test the entire length. If we find any defect indication, it is necessary to crosscheck and conform the defect signal, and size the defect. So by this discussion we start with a basic idea “LRUT is a Screening tool, can not judge the defect size or depth.
