摘要
Abstract
The detection and analysis on defects and forming reason of some oil and gas transportation pipeline circumferential weld were conducted through X-ray detection, metallographic analysis, scanning electron microscope (SEM) and energy spectrum analysis. The result showed that some defects existed in circumferential welded joint, such as weld beading, porosity, indent (weld incompletely filled), incomplete fusion and slag inclusion, stress concentration easily appear in defect, turn into crack source. It suggests in welding operation of oil and gas transportation pipeline circumferential weld, on the one hand, to guarantee assembly accuracy of pipe end to decrease the possibility of offset and incomplete fusion in side wall;on the other hand to choose suitable welding method.关键词
