Influence of GMAW-P Pulse Parameters on Welding Process and Weld Size

摘要: 采用三因素三水平正交试验方法,结合高速摄影、焊接电参数采集、金相检测等手段,分析了脉冲电流、脉冲时间、脉冲频率等参数对焊缝成形及焊接过程稳定性的影响规律。结果表明,在所选的3个脉冲参数中,脉冲频率对熔深和焊接过程稳定性的影响较大,脉冲电流对熔宽的影响更大。

Abstract: The influences of pulse current, pulse time, pulse frequency and other parameters on the weld formation and the stability of welding process were analyzed by using there-factor and three-level orthogonal test, combined with high-speed photography, welding electrical parameter acquisition, metallographic detection and other means. The results showed that among the three pulse parameters, the pulse frequency had a great effect on the penetration and welding stability, while the pulse current had a great effect on the weld width.
