【 摘 要 】

This paper describes the remaining wall thickness assessment using Ultrasonic Testing Phased Array (UTPA) technique. A steel plate of thickness 15 mm consists of machined simulated corrosion with various thicknesses, depths, shapes, and sizes were used in this work. Manual corrosion scanner is attached with GE Phased Array (PA) thirty-two elements (transmitter and receiver) Dual Matrix probe of 5 MHz with 1.5 mm pitch is used. The scanner then applied firmly on the plate to execute the inspection. From the result, the relevant indications from the A, B and C-Scans display are collected and analysed. The outcome of the study revealed that UTPA technique is capable to collect a high density of measuring point of thickness compared to the conventional UT technique such as Ultrasonic Testing Thickness Gauge (UTTG).
