“…Projected multiple displays such as A-scan, B-scan, S-scan, and C-scan helps the operator to improves the detecting, locating, and characterising and sizing of defects, which is essential in SHM of engineering component in the industry. Limitation from the A-scan of conventional UT could lead to misinterpretation of sizing due to the SNR effect [6]. UTPA accurately detected the locating, detecting, characterising and sizing of the internal weld discontinuities compared to UT.…”

“…This technique is capable of inspecting complex geometries that are difficult to access using conventional UT. It is capable of inspecting almost all solid material where traditional UT methods have been practiced and are often used for weld inspections and crack detection [3,6]. The welding process is also an essential part of building a structure, especially in the metal structure.…”

Non-destructive testing (NDT) is a method of testing and analysis that rely on the application of physical principles to determine the integrity of materials without causing damage. The existence of weld discontinuity can affect the service ability of the materials. Ultrasonic testing Phases Array (UTPA) is widely practiced in many industries. The multiple ultrasonic elements and electronic time delay will create a constructive and destructive interference which could lead to mis-interpretation and evaluation of data. This multi displays scan capable to inspect complex geometries which are difficult to access using conventional UT. Two carbon steel plates with thickness 18 mm and 24 mm were prepared and cut to V-shape configuration and welded using shielding metal arc welding (SMAW) process, labeled as NDE-8826 and NDE-8827 respectively. Both samples were induced with internal weld. The samples will undergo A-scan, S-scan, B-scan, C-scan and Azimuthal scan to identify weld discontinuity. The length and datum of toe crack, slag and lack of inter run fusion detected by UTPA in NDE-8826 gives the same value as actual value. However the localization of the defect is slightly different at 1.0 mm for UT detection. While, the detection value for slag gives the same values for UT and UTPA which also same to the actual values. The detection of lack of penetration and lack of fusion in sample NDE-8827 was precisely can be detected by UT and UTPA, however their datum value has slightly different in centre line crack and porosity at 2.0 mm for UT measurement. As for UTPA, it was found that the porosity measurement gives 3.0 mm higher value compared to actual value at 250 mm. As conclusion, the multi displays scan, A-scan, B-scan, Azimuthal scan, S-scan and C-scan could help the UT and UTPA in detecting the weld discontinuity in carbon steel plate. However, both instrument need improvement in detecting porosity of the samples.
