运载火箭贮箱铝合金焊缝补焊后需要采用被列入航天科技集团公司限制使用的着色渗透方法检测表面缺陷.本文分析了铝合金熔焊缝的特点,研究了铝合金熔焊缝不同区域对电导率的影响和焊缝表面形状对涡流检测信号的影响.检测结果表明,采用阵列涡流检测方法可以检测出3.0mm×0.2mm×0.3mm的人工槽缺陷.
The previous studies of real-time imaging process use direct delay calculation design on FPGA,because the restricting number of memory on chip.In this paper,to achieve higher frequency,a look-up table

New laser interferometric schemes were recently developed in order to measure three components of the ultrasonic field.The TEMPO 3D is a tri-component,two-wave mixing interferometer capable of simulta
When the solid axle is detected by the conventional ultrasonic probes,the inspecting coverage of axle is very limited,especially for the press-fit part of axle where the signal-to-noise ratio of detec
