Abstract Welded pipes are particularly susceptible to rapid degradation. Cracks can be detected during regular inspections, either mandated by the welding-filling process or by employing more intrusive methods like cutting and replacing sections. Such small discontinuities can evolve into fatigue cracks or stress corrosion cracks during service. Welding process parameters significantly influence fabricated joint quality. The characteristics of welding are crucial in the industrial sector, particularly in the manufacturing sector. One key process for ensuring the quality of welding is the post-welding non-destructive test (NDT), although it is both time-consuming and expensive. To minimize the occurrence of defects, online monitoring has been used to continuously measure certain welding parameters and forecast the quality of the weld. The objective of this study is to assess the dependability of non-destructive test (NDT) methods for examining pipeline welds used in the oil and gas industry. Techniques, includes ultrasonic methods manual and automatic, digital radiography, manual and automatic were utilized. Pipe discontinuities includes- lack of fusion, lack of penetration, porosity, slag, off-seam under cut, crack etc. The experiments were conducted on samples from pipelines that had been developed during the welding process. The findings indicate that automatic ultrasonic tests are more effective in detecting defects compared to manual ultrasonic and radiographic tests.
