摘　　要：研究PC-MIG焊时,通过改变缓送丝引弧的送丝速度、脉冲能量参数,以及焊丝外伸长度上的局部位置电阻值等对电弧引燃特性与引弧段焊缝成形质量的影响进行了研究,研究结果对生产有指导意义。Arc stability and characteristic in arc striking process, and quality of weld beam forming in arc starting zone are found to be strongly influenced by the changes of slow wire feed speed, energy parmeters of pulse current and resistance of electrode extansion in PC-MIG welding process. The results from investigation will be taken as a guide for production.
