各向异性焊缝相控阵超声检测楔块角度的优化设计
Optimization design of wedge angle for phased array ultrasonic detection of anisotropic welds
摘 要
超声波在各向异性介质中传播时，超声衰减值和声速大小会随声波入射角度的变化而改变，因此针对各向异性焊缝相控阵超声检测的特点，提出了一种通过优化探头楔块角度来获得最佳入射角度的工艺方案。首先，利用电子背散射衍射法评价焊缝的显微结构，基于Silk模型建立了焊缝各向异性模型；其次，运用CIVA仿真软件计算不同楔块角度、不同检测距离对应的反射幅值；最后，对数据进行综合分析，确定最优化的楔块角度以获得最佳的反射信号幅值。运用优化设计方案对奥氏体不锈钢小径管对接焊缝试样进行数值仿真和检测试验，结果表明，通过使用角度优化后的探头楔块的相控阵检测仪，可以很好地实现奥氏体不锈钢的焊缝检测，使缺陷定位更加准确，为奥氏体不锈钢焊缝检测工艺优化提供了可行的技术方案。

Abstract
Sound attenuation and speed change along with incidence angle of ultrasonic wave. According to the characteristics of phased array ultrasonic detection applied in anisotropic weld, a process scheme for obtaining the optimum incidence angle by optimizing the wedge-angle is designed. Firstly, electron back scatter diffraction technique is used to evaluate the texture of the weld. The anisotropy model was established based on Silk model. Secondly, CIVA simulation software is used to calculate the reflection amplitude corresponding to different wedge angles and detection distances. Finally, data are analyzed comprehensively to determine the optimal probe wedge angle for obtaining the optimal reflection amplitude of signal. The numerical simulation and test of butt weld specimens of small-diameter pipes (austenitic stainless steel) are carried out by using the optimized design scheme. The results show that the optimized probe wedge can be well used in testing the weld of austenitic stainless steel and locating the defect. This research work provides a feasible technical scheme for the inspection of austenitic stainless steel weld.
