摘要

为优化Q350EWR1高耐候钢的脉冲MAG焊接工艺。通过在开启脉冲宽度调制（PWM）反馈的条件下，借助高速摄影和记录仪观察电弧的形态以及焊接电流和电弧电压波形，调整不同送丝量的熔滴脱落时机和熔滴过渡的一致性。找出最优的脉冲频率、脉冲上升斜率、脉冲下降斜率、脉冲峰值、脉冲基值，保证焊接电弧的稳定性，有效控制飞溅量，节省焊材且提高了焊接生产效率。并在松下GS6焊机上得到应用，为Q350EWR1高耐候钢的焊接工艺提供了参考依据。

In order to improve the welding performance of Q350EWR1 high weather resistant steel

this article adopts pulse welding method. By using high-speed photography and recorders to observe the shape of the arc

as well as the waveform of welding current and arc voltage

under the condition of pulse width modulation (PWM) feedback

adjusting the timing of droplet shedding and consistency of droplet transition for different wire feed rates. Find out the optimal pulse frequency

pulse rise slope

pulse fall slope

pulse peak value

pulse base value to ensure the stability of welding arc

effectively control the splash amount

save welding materials and improve welding production efficiency. It has been applied in the GS6 welding machine developed by Panasonic

which provides a valuable reference for the welding process of Q350EWR1 high weathering steel.
