This is a comparison test to verify the defect location accuracy and the impact of calibration between third-party equipment and DEEPSOUND P5.
Test Setup
The probe and wedge configurations of the two systems are as follows.
Third-party Equipment Probe Specifications
Third-party Equipment Wedge Specifications
Test Specimen
P5 Equipment Probe Specifications
P5 Equipment Wedge Specifications
P5 Equipment Scan Configuration Settings
PA & DA Comparison: Defect Identification
The parameters and defect measurement criteria for third-party equipment and DEEPSOUND P5 were set and verified as follows.
Image Results
A direct visual comparison of S-scan images acquired from both devices.
Detailed Evaluation
Additional comparison of detected signal quality and positional accuracy.
Comparative Data Verification
Analysis of the difference between locations detected by the two systems.
Conclusion
As a result of the comparative analysis, we confirmed that applying Wedge delay calibration causes differences in PA and DA readings on both devices.
Even though wedge delay was activated and applied to both systems, minute differences remained from the actual physical location of the defects.
Overall, the detection capability and accuracy for precisely locating defects were proven to be very equivalent between DEEPSOUND P5 and third-party equipment.
