多层钎焊结构件超声C扫描信号特征分析

Analysis of Characteristic of Ultrasonic C-Scanning Testing for Braze Quality of Multi-Layer Welding Line

对多层钎焊件内层焊缝检测中产生的多重声束路径叠加现象进行了详细分析,并用计算机模拟超声检测中的叠加信号,总结出对等厚薄板钎焊缝阵结构内层焊缝的检测方法及C扫描时信号门放置的合理位置,并且在实际检测中验证了该方法的正确性。

The superposition of ultrasonic wave in the ultrasonic C-scanning testing for braze quality of multi-layer welding line is discussed minutely in this article.The simulation for the ultrasonic wave by different path is made.The result of experiment testifies the accuracy of this research.
