About Phased Array inspection
In contrast to conventional ultrasonic testing using single-transducer testing technology, phased array testing offers a wider range of applications thanks to the free design of sound fields. Linear and sector scans enable a high degree of automation.
Phased array testing places high demands on the education and training of test personnel. In the run-up to your projects, our engineers and technicians simulate the sound path in order to determine optimised setups for the test.
At TÜV AUSTRIA Group, phased array testing is carried out exclusively by certified personnel in accordance with all national, European and international standards.
Advantages of Phased Array inspections
- Inspection with multiple beam angles during sector scan (efficiency and reliability of findings)
- high volume coverage, with limited geometry of the test object
- In advance, the ultrasonic trajectories are simulated in order to determine the optimal inspection technique.
- Same results as with radiographic inspection but: increased testing speed
- no complex radiation protection measures
- Wall thickness range up to 300mm normatively testable without the cost-intensive use of a linear accelerator
Area of application
Phased array testing is particularly suitable for applications that require high defect resolution and high testing speeds. It is also used for recurring inspections and as part of RBI programmes for corrosion mapping and the inspection of pipes and pipe bends, among other things.
