X80钢管施工常见焊接缺陷和质量控制措施

Common Welding Defects in the Construction of X80 Steel Pipe and Its Quality Controlling Measures

以目前正在施工的中卫-贵阳联络线输气管道工程焊接中易产生的各类常见缺陷为例,说明了各类缺陷形成的原因和预防措施,指出了日常外观检验和无损探伤中应注意的几个问题。

By an example of all kinds of common defects appearing easily in the present welding construction of gas pipeline project on the connection line between Zhongwei and Guiyang, the paper presents the formation causes of all defects and corresponding prevent measures. Then it is pointed out that several problems in daily observational examination and nondestructive flaw detection should be paid much attention.
