PHASED ARRAY ULTRASONICS
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
Why Use Phased Array
High speed electronic scanning without moving parts
Improved inspection capabilities through software control of beam characteristics
Inspection with multiple angles with single, electronically controlled probe
Greater flexibility for inspection of complex geometries
Optimized beam angle
Basics of How They Work
Ultrasonic phased arrays consist of a series of individual elements, each with its own connector, time
delay circuit, and A/D converter
Elements are acoustically insulated from each other
Elements are pulsed in groups with pre-calculated time delays for each element, i.e., “phasing.”
For economic reasons, pulsers are usually multiplexed
Instrumentation nomenclature such as a PA 16/128 refers to an instrument with 16 multiplexed
pulsers and a total of 128 ultrasonic channels.

What Courses Are Offered?
Phased Array Level 2 (80 Hours), Assessment approved for AS3998/AINDT certification.
Ultrasonics Phased Array Level 2 Welds
(Includes AINDT Approved Examinations for Phased Array Certification)
Duration: 10 Days
Purpose: To train personnel in detection, measurement and recording of discontinuities in Welds
using Ultrasonic Phased Arrays. (Based on the method code AS2207)
Due to the variances in equipment available, two competencies are available:
1) Manual Phased Array Inspection
Real time inspection and interpretation (for systems not containing data collection
or encoded scans).
2) Encoded Phased Array Inspection
Encoded data collection and interpretation.
Note: Satisfactory completion of Encoded Phased Array encompasses Manual
Phased Array Inspection.
