The Application of Phased Array on Offshore Small Diameter Butt Weld Pipeline Testing

摘要: 针对相控阵超声对海洋工程平台小径管对接焊缝的检验，使用CIVA软件进行建模仿真，根据仿真试验给出了相对最优的检测工艺，并进行了检测验证，证实了相控阵超声探伤技术在海工小径管对接焊缝检测领域的优势，为海洋工程小径管对接焊缝的探伤方法探索出一种可行的途径。

Abstract: For the purpose of the inspection small diameter butt-weld pipeline with technology of PA, the CIVA is applied for simulation.The optimum procedure is provided and verified based on the simulation. As the result of above, the advantage of Phased Array technology is validated, which explores the feasible way for offshore small diameter butt weld testing.
