摘要:
针对钛合金贮箱制造检测工艺过程中经常发生的质量偏差,通过对球形钛合金贮箱两例异常声发射幅度、时间历程以及定位结果等进行综合分析。结果表明,声发射检测技术对贮箱制造工艺状态偏差具有很强的敏感性,声发射检测结果不仅能反映贮箱产品的强度质量,还能反映贮箱制造工艺状态的稳定性和偏差。

Abstract:
In view of the quality deviations that often occur in the process of manufacturing and inspection of titanium alloy tanks, a comprehensive analysis of the acoustic emission amplitude, time history and positioning results of two cases of abnormal spherical titanium alloy tanks was carried out. The results show that the acoustic emission detection technology has a strong sensitivity to the deviation of the tank manufacturing process state. The acoustic emission detection results can not only faithfully reflect the strength and quality of the tank product, but also reflect the stability and deviation of the tank manufacturing process state.
