| 摘 要： | 具有多尺度(分辨)分析和时-频局部化特性的分形分析技术,特别适用于边缘信号和峰值突变信号的处理和特征提取,因此在焊接过程中缺陷检测和诊断将会有很大的发展前途。用分形变换的方法对焊接过程中进行初步缺陷检测和诊断,结果表明分形分析在焊接过程中缺陷检测和诊断有很好的应用前景。 |

| Abstract: | It is specially adapted to process the brim signal and the sudden(or quick)variations of signal for the fractal geometry technique,which is a multiresolution analysis and has a good localizing feature.There will be a very good outlook in fault detection and diagnosis.This paper takes the wavelet analysis transformation as the means to process the fault detection and diagnosis of the jointing.The research result is inspiring. |
