摘要: 文中借助HANNOVER电弧分析仪和高速摄像机等设备，对不同电弧电压和焊接电流焊接过程进行实时监测，分析不同电参数对焊缝成形质量的影响；并验证激光的存在对波形的稳定具有一定的作用. 结果表明，主辅“双重导电通道”的消失、熔滴过渡方式跳变和焊接飞溅等不确定因素，均会导致电弧电压、电流波形图出现紊乱和尖角. 焊缝成形方面，随着电弧电压的增加，熔宽先增大后减少；而熔深则不断上升. 而电流增大时，焊缝的熔深熔宽不断增大. 因为电弧电压增大，改变了电弧的形态；而电流的增加则改变电弧的受力和能量.Abstract: By using HANNOVER arc analyzer and high-speed cameras, different arc voltage and welding current welding process were monitored on real-time，and the influence of different electrical parameters on the quality of welding were analyzed . And that the effect of the laser presence on the stability of waveform was verified. It is found that main and auxiliary “double conductive channel” disappeared, droplets transfer mode transition and welding splash and other uncertain factors leading to disorder and sharp angle of the waveforms of voltage and welding current. In the weld forming, as the arc voltage increases, the melt width increases first and then decreases, while the penetration depth is rising. When the current value increases, the penetration depth and width of the weld also increase. Because the arc voltage increases, the form of arc is changing. The arc force and energy are also changing the increase of current.
