摘　　要： 搭建由双丝数字化焊接电源系统组成的焊接工艺平台,通过大量工艺试验,全面测试所设计的双丝电源工艺性能。通过对比分析采集的电压、电流波形和焊缝,进一步确定双丝电流差值对双丝焊接效果的影响规律。实验结果得到最优电流差值范围,使双丝数字化焊接电源能有效实现双丝CO2焊接,且焊接质量优异。 By utilizing the developed twin - wire digital welding power system,this paper established the welding technological platform. Then a large number of technological experiments have been carried out to fully test the designed twin - wire poer process performance. through the contrast analysis the aacquisition of current,voltage waveforms and welding bram,to further determine the tein - wire current difference influence law of twin - wire weding effect. The experiment to get the best range of pulse current difference that the digital twin - wrie welding power system could achieve twin - wire CO2 welding effectively,and the welding quality is excellent.
