衍射时差法 (TOFD) 具有检测信息丰富、抗噪声强、效率高、定位定量

衍射时差法 (TOFD) 具有检测信息丰富、抗噪声强、效率高、定位定量准确等优势,广泛应用在焊缝检测中,而TOFD图谱判别主要依靠人,存在效率低、主观性大、可靠性低等问题。为了提高缺陷类型识别的准确性及效率,结合TOFD图谱和波形特征,构建了一种级联融合卷积神经网络(CNN-TCN),对焊缝缺陷扫描图像中的缺陷类型进行自动识别。结果表明: 基于CNN-TCN的分类精度明显高于单纯的lenet5和TCN方法,缺陷类型的识别率可达到88%以上,说明综合考虑TOFD焊缝缺陷的图像特征和其超声波序列的波形特征,对于提高TOFD焊缝缺陷的分类准确率有较大的作用,并具有高识别率、鲁棒性和抗干扰能力。

Time-of-Flight Diffraction (TOFD) has the advantages of rich detection information, strong anti-noise, high efficiency, and accurate positioning and quantification. It is widely used in weld inspection, while TOFD map discrimination mainly relies on people, with low efficiency, high subjectivity, and reliability Low-level issues. In order to improve the accuracy and efficiency of defect type recognition, a cascaded fusion convolutional neural network (CNN-TCN) is constructed by combining TOFD map and waveform characteristics to automatically recognize the defect type in the weld defect scan image. The results show that the classification accuracy based on CNN-TCN is significantly higher than the pure lenet5 and TCN methods, and the recognition rate of defect types can reach more than 88%. It shows that the image characteristics of TOFD weld defects and the waveform characteristics of its ultrasonic sequence are considered comprehensively. Improving the classification accuracy of TOFD weld defects has a great effect, and has high recognition rate, robustness and anti-interference ability.

TOFD has many advantages, such as abundant detection information, strong noise resistance, high efficiency and accurate positioning, and is widely used in weld detection. TOFD spectrum discrimination mainly depends on human beings, which has low efficiency, high subjectivity and low reliability. In order to improve the accuracy and efficiency of defect type recognition, a cascade fusion convolutional neural network (CNN TCN) is constructed based on TOFD and waveform characteristics to automatically identify the defect types in the weld defect scanning image. The results show that the classification accuracy of CNN TCN is significantly higher than that of lenet5 and TCN method, and the recognition rate of defect types can reach over 88%. It shows that considering the image characteristics of TOFD weld defects and the waveform characteristics of ultrasonic sequence, it has a great effect on improving the classification accuracy of TOFD weld defects, and has high recognition rate, robustness and anti-interference ability.<br>
