Ultrasonic testing of vacuum brazed ring superalloy part
-
摘要: 以某封严环组件为研究对象，采用水浸超声检测技术，通过监测结合层处的超声回波幅值来分析检测分辨率和穿透力，进而评判真空钎焊结合质量。试验分析得出环状高温合金真空钎焊件的最佳检测参数，并将其运用于实际零件检测。检测结果表明，超声检测能及时发现焊接质量不良位置，具有一定的应用价值。Abstract: In this paper, a sealed ring assembly is taken as the experimental research object. By monitoring the ultrasonic echo amplitude at the bonding layer, the detection resolution and penetration force are analyzed, and the quality of vacuum brazing bonding is evaluated. The optimum testing parameters of annular superalloy vacuum brazing parts are obtained and applied to actual parts testing. The test results show that ultrasonic testing can find the position of poor welding quality in time, which has certain application value.
