摘　　要：通过对脉冲MAG焊和脉冲MIG焊进行研究,利用焊机自身的功能,在相同的焊接电流和焊接电压条件下,调整焊机的脉冲特性;且在相同的脉冲特性下,调整焊接电流和焊接电压,从而获得了电弧宽度与脉冲特性、焊接电压、焊接电流及脉冲波形占空比的关系。试验结果表明:焊接电流和焊接电压相同时,电弧宽度随着脉冲特性的增大而增大;脉冲特性相同时,电弧宽度随着焊接电流和焊接电压的增大而增大。In the study of pulse MAG welding and pulse MIG welding, using the function of the welding machine itself, the connections between arc width and pulse characteristics, welding voltage, welding current and duty cycle of pulse waveform were obtained when the pulse characteristics being regulated with the same welding current and welding voltage or the welding current and welding voltage being regulated with the same pulse characteristics . The results showed that with the same welding current and welding voltage, arc width increased with the enlargement of pulse characteristics and in the same pulse characteristics, arc width enlarged with the enlargement of welding voltage and welding current.
