Ultrasonic Phased-Array (UT PA)
Phased array testing is an ultrasonic technique in the field of non-destructive testing (NDT) that detects both manufacturing defects and operational damage, such as cracks.
Ultrasound from different perspectives
Phased array ultrasonic testing is used for defect detection, wall thickness measurement and even corrosion testing. Since this method allows different beam angles and focal depths to be combined with a single probe, allowing different inspections to be performed without changing the transducer arrangement, the phased array method is extremely efficient and cost effective. This technology can be used wherever conventional ultrasonic testing is used. The visual representation of the test results is stored electronically and is available for subsequent assessment and evaluation. Phased Array is suitable for metallic materials and carbon fibre reinforced plastics (CFRP).
Applications:
- Weld seam testing (also in mechanized testing)
- Examination for corrosion
- Wall thickness measurement
Advantages of Phased Array tests
-
Tests on specimens with complex geometries
-
Significantly higher inspection speed than conventional ultrasonic inspection
-
If recording of the test is corruptible
-
If the standard specifies several beam angles (cost reduction)
-
High error detection due to different beam angles
-
Graphical display of test data
