| description | The invention discloses a determination method and device for eddy current testing sensitivity. Specifically, the method includes: scanning to-be-detected alloy weld seams; acquiring an amplitude value distribution curve of the to-be-detected alloy weld seams' eddy current testing signals according to the scanning result; and determining a maximum amplitude value of the eddy current testing signals according to the amplitude value distribution curve of the eddy current testing signals, wherein the maximum amplitude value is used for identifying the sensitivity of eddy current testing on alloyweld seams. The method and device provided by the invention solve the technical problems of low accuracy and long time in determining the sensitivity of eddy current testing on metal butt welds in related technologies.
本发明公开了种涡流检测灵敏度的确定方法及装置。其中，该方法包括：扫描待检测合金焊缝；根据扫描结果，得到待检测合金焊缝的涡流检测信号的幅度值分布曲线；根据涡流检测信号的幅度值分布曲线，确定涡流检测信号的最大幅度值，其中，最大幅度值用于标识对合金焊缝进行涡流检测的灵敏度。本发明解决了相关技术中在确定金属对接焊缝的涡流检测的灵敏度时，准确度低、耗费时间长的技术问题。 |
