摘　　要：初步探讨如何采取时间序列分析的方法对焊接结构、焊缝的缺陷进行诊断,并获得能够反映系统状态的参数,从而判断出焊缝质量的不同情况.This paper discusses how to adopt the method of time series analysis to diagnose the welding structure and weld defect and the system parameters can be deduced which can reflect the system condition. And the weld quality of different situations can be determined with the system parameters, by which we can tell the weld quality.

关 键 词：时序法 焊缝损伤 诊断
