摘要: 分析了衬里复合材料的检测难点,基于相控阵AUT(自动超声检测)技术,制作了一系列焊接缺陷,并对比分析缺陷的AUT检测结果与缺陷宏观切片结果,评估AUT对于不同位置缺陷的检出率及缺陷定量精度,验证了衬里复合材料焊缝AUT检测的可靠性。Abstract: This paper analyzes the difficulties in the detection of lining composite materials. Based on the phased array AUT detection technology, a series of welding defects were made, and the AUT detection results of defects and the macro sectioning results of defects were compared and analyzed. The detection rate and quantitative accuracy of defects at different positions were evaluated, and the reliability of AUT detection of lining composite welds was verified.
