Abstract

Ultrasonic testing (UT) are the most common technique used for composite laminated non-destructive (NDT) inspection. In the current practice, the dependency of human interpretation during perform UT resulted in inequality detection issues on inspection process step. This paper presents an improvement of UT approach using graphical user interface (GUI) to provide defect percentage of C-scan image. Several of composite laminated C-scan defect image was identified before the defect percentage being calculated. The intensity difference between defect and non-defect image was calculated in this GUI. Base on this experimental results shows that the result of defect calculation was reliable which is proved by calibrated image. The different between an ideal and actual defect calculation is 0.69 % are considered insignificant and negligible. The average execution time for three test series is between 7.35 sec to 8.52 sec while the longest time is 9.52 sec. Since the execution time is not exceed 10 sec and acceptable. Instead of application, this GUI, however, able to operate only in offline and flat surface condition.
