Analysis of arc stability of self-shielded flux-cored wire laser-arc hybrid

  • 摘要: 以自保护药芯焊丝(414N-O)为研究对象,借助电弧分析仪和高速摄像,对不同工艺参数下激光—电弧复合热源焊接电弧稳定性进行了试验研究.结果表明,复合热源焊接过程中,激光的加入明显的减小了自保护药芯焊丝电弧作用点漂移概率,拉长了电弧空间,降低了熔滴短路过渡概率,提高了电弧稳定性;工艺参数中,光丝间距和送丝速度对平均焊接电流影响显著;电弧电压和送丝速度对平均焊接电流变异系数影响显著;激光功率对平均焊接电流的影响幅度与光丝间距和送丝速度有关,光丝间距和送丝速度越大,激光功率对平均焊接电流的影响越小;电弧电压对平均焊接电流的影响幅度与光丝间距有关,光丝间距DLA=0 mm时,影响最显著;激光前置比激光后置更有利于平均焊接电流变异系的稳定.
    Abstract: The influence of arc stability on different process parameters during Laser-arc hybrid welding which used self-shielded flux-cored wire (414N-O) with the help of Hannover Analysator and high speed photography were studied. The results indicated that the probability of arc point drift and short circuiting transfer of self-shielded flux-cored wire are reduced with the addition of laser. Oppositely, arc length is elongated and the arc stability is improved. In the parameters, the distance between laser and arc(DLA) and wire feed speed have appreciable impact on the mean actual output current, and the stability of current coefficient of variation.is significantly affected by welding voltage and wire feed speed. The influence range of laser power to mean actual output current is related to DLA and wire feed rate, and the influence declines with DLA and wire feed rate increase. The influence range of welding voltage to mean actual output current is related to DLA and it has the greatest impact when DLA is 0 mm. Laser leading is more beneficial than laser trailing to the stability of current coefficient of variation.
