| 摘 要： | 为了进一步了解双丝焊接过程中电弧干扰的规律以及有规律的断弧现象,设计了不同焊接电流参数值的匹配系列试验,同步拍摄了电弧形态并采集了两电弧的电流、电压波形.通过理论推导出的双丝电弧的偏移量公式分析了上述试验结果并得到了基本符合的结论：增大另一电弧与该电弧的电流比例,该电弧中断频率增加.最后将高速摄影拍摄到的电弧图片与采集...

| Abstract: | In order to get a further understanding the principle of electromagnetic interaction and study the regular phenomenon of arc interruption during the double-wire GMAW welding process, a series of experiments of different current matching are designed, then taking a picture of arc shape and collecting current and voltage waveforms simultaneously during the welding process. Analyses for the above-mentioned experiment results with displacement formula derived through the theory of electromagnetic then gets the same conclusion:the increase of another arc with the arc current ratio will increase the frequency of interruption of the arc. Finally, combining the captured images of the arc with the acquisition of current, voltage waveforms and analyzing the arc interruption phenomenon, the results show that the arc interruption phenomenon can be avoided by reasonable matching of welding parameters. |
