摘要
针对锅炉所存在的泄漏缺陷,提出了一种声发射逐点监测方法,然后结合声发射信号幅度历程和波形频谱分析法,通过现场检测实例验证了该方法用于锅炉泄漏缺陷声发射检测的可行性与准确性。
For the leak defects of boiler,apoint by point monitoring method with acoustic emission testing is firstly presented.Afterwards,through the combination of amplitude and waveform analysis method of acoustic emission signal,the feasibility and accuracy of the method for acoustic emission testing of boiler＇s leak defects are verified with a field test.
