Technology Background

Phased Array Ultrasonic Testing (PA UT) uses a single transducer containing multiple elements (16 to 128) to send angle beams of sound through the test object. Each element can be individually pulsed to send out timed sound waves, in phases. This creates several beam angles, which combine to make an array. This array identifies changes in the material, such as cracks or inclusions, and shows these indications on the screen.

These diagrams demonstrate some of the capabilities of the beam spread; to allow full coverage of a weld or processed assembly during in-process inspection.

With multiple beams, complete scanning coverage of a product is achieved with very little manipulation of the probe.  Many codes and standards require that complete coverage must be demonstrated.

Phased Array UT meets this requirement in an extremely cost effective manner.

High-Tech Reporting (Digital & Paper) – Real Time Data Aquisition / Collection

ECE Global performs semi-automated Phased Array UT, achieving real time data acquisition and collection. This data may be stored and reviewed at a later date and used as data entry information for statistical processes. Scans can be saved as digital files in different media types, (e.g. CD, DVD, flash drive, hard drive)., and made available for review or print. Available data programs may be used to create reports, or piece many scans together to provide an area view of a surface.

Save Time – Save Money

• Minimal manipulation of probes for complete weld coverage leads to accurate, rapid sizing and location of indications
• Fast, accurate identification of indications reduces repair time
• PA UT does not require a “safety zone”, allowing less interruption to production during testing
• Results can be viewed immediately, and saved to equipment, eliminating development delays for viewing
• The ability to show multiple views simultaneously results in quick identification of indications in real time and eliminates the need for reshoots, common with RT
• The re-inspection of repairs also enjoys all the same cost saving benefits as well.

Pro’s and Con’s

Advantages:		Disadvantages:
Real time acquisition		Direct access to material required
Location and sizing		Not suitable for small piping
Continuous production		Operator dependent
Quick reliable results
Safer than Radiography
