中文摘要: |
本文以焊缝超声检测常见的缺陷(夹渣、气孔、未焊透、未熔合)为对象,选取缺陷时域波形的上升时间、波宽、上升角度和频域特征的波动次数、底宽等特征值组成特征矢量作为ART-2的输入,来实现缺陷性质的识别,并与射线检测结果对比。实验结果表明:采用该方法得到的正确识别率达到81.5%,具有良好的应用前景。 |
英文摘要: |
Based on the four types of weld flaws in Ultrasonic testing,this paper presents the ART-2 method to recognize the defect pattern.Five characteristics in the time do- main and frequency domain are chosen as the input vector for the ART-2 network.The results were compared with those of X-Ray testing.Experimental results show that the recognition rate can reach 81.5% due to the method and it has a future for applications. |
