    摘要
  • 摘要: 统计分析了不同环境压力下脉冲MAG焊的电流电压波形和数据,探讨了其概率密度分布规律与高气压环境下焊接电弧稳定性的关系. 结果表明,随着环境压力增大,能量损失加剧,焊接过程越不稳定. 为了获得高气压环境稳定的焊接过程,采用提高电弧电压的方式来补偿电弧能量损失. 在0.3和0.5 MPa压力环境下,电弧电压分别提高3和5 V时,焊接过程可与常压环境相当. 提高电弧电压方式对高气压环境下焊接稳定性的提高具有显著的作用,该研究可为高气压环境下脉冲MAG焊参数优化匹配提供理论依据与试验基础.
    Abstract: The pulsed MAG welding current and voltage waveforms in different air environmental pressures were analyzed using statistical method. The relationship between probability density distribution of arc voltage and current and the hyperbaric welding arc stability under different ambient pressure were also investigated in this paper. It is shown that the arc energy loss intensifies with increasing the environment pressure resulting in less stable welding process. A useful method to raise arc voltage setting to compensate the arc energy loss was used to obtain stable welding process. When arc voltage setting was increased 3 V and 5 V respectively in 0.3 MPa and 0.5 MPa hyperbaric environment, a stable welding process comparable with normal atmospheric welding has been realized. It is concluded that welding stability of hyperbaric pulsed MAG welding arc can be improved by higher arc voltage. This paper provided theoretical basis and experimental foundation for the hyperbaric pulse MAG welding to optimize and match the welding parameter.
