| Abstract: | In this article, it analyzed base metal imperfections adjacent to SAWL pipe weld and the causes of imperfections confirmation difficuhy, and introduced the hazard and main types of imperfections, such as laminations, inclusions, cracks and so on. It put forward dissent for discordance of determining the above imperfections in corresponding specifications. Through verifying NDT and metallographic test results of base metal imperfections adjacent to weld, it summarized defect positioning and qualitative methods, which provides simple and feasible handling methods of preventing imperfections adjacent to weld for welded pipe manufacturers. |
