介绍灵巧的两维和三维柔性相控阵换能器,用于检测几何形状复杂的焊接结构中裂纹类面状缺陷的方法特征和优势。新的实时功能,能重建内外表面轮廓;全点聚焦(FTP)法,能有效改善内表面开口裂纹的成像效果。期盼此法对承压设备复杂结构的超声检测,开辟新通道。
Dexterous two-dimensional and three-dimensional flexible phased array transducers are introduced to demonstrate the methodological features and advantages of crack-like planar defects in complex geometrically welded structures. The new real-time feature that rebuilds the contours of the inner and outer surfaces; the all-point focus (FTP) method effectively improves the imaging of open-face cracks in the inner surface. Look forward to this method of pressure equipment for complex structures of ultrasonic testing, open up new channels.
