英文摘要	By applying the embedded system control to carry out the control tests for consumable DE-GMAW, the welding process is unstable, main arc and bypass arc are affected each other, bypass arc length is unstable, bypass current changes seriously, and there is welding defects and poor weld appearance in open loop welding. Stability test of the welding process based on the arc voltage feedback prove that the embedded system can feedback arc voltage in real time, adjust bypass wire feeding rate and control the bypass arc length, make sure welding process stable. Stability test of the welding process based on the current control shows that the embedded system can feedback the bypass current in real time, judge the bypass current change trend, adjust the bypass current in real time, ensure current in base metal to be stable. Applications of the embedded system control of both bypass wire feeding and bypass current ensure stable welding process, avoidiance of welding defect and good weld appearance.
