摘要
对小径管对接接头中存在的裂纹、未熔合和未焊透等自然缺陷分别进行相控阵超声检测和射线检测,比较分析了两种检测方法的检测结果,评述了相控阵检测的优势及其在小径管检测中的应用前景。
The small diameter pipes butt welds with natural defects such as crack, lack of fusion, lack of penetration and so on were inspected by both phased array(PA) ultrasonic inspection technology and radiographic testing technology. The results with up two inspection technologies were compared and analyzed. The advantage, and application prospects of PA technology in the field of inspecting small diameter pipes were overviewed.
