摘　　要：针对薄壁长输管道对接焊缝的具体特征 ,选择合适的超声波检测工艺参数 ,并通过一系列模拟试样的实验 ,探讨 6.4mm厚薄壁长输管道超声检测方法的可靠性 。The suitable technological parameters for ultrasonic testing should be selected in accordance with the character of thin wall long distance pipelines. After the experimental research on a series of test specimens, the reliability of ultrasonic testing of the butt welded seams in thin wall long distance pipelines is analysed and proved by jobsite testing.
