  • 铝合金熔化极惰性气体保护焊(MIG)的亚射流过渡方式具有弧长调节作用强、焊缝成形美观的优点.本文从非线性动力学近似熵测度的角度对铝合金脉冲MIG焊的电弧电压信号进行分析,进而评价自适应控制模式针对亚射流过渡方式的适用性;讨论在自适应控制模式下,改变工艺参数和熔滴过渡方式时,近似熵值的变化;并对比自适应控制与普通脉冲控制在射滴过渡方式下的近似熵值大小.结果表明近似熵越小,自适应控制越成功,控制越有效.
    The meso-spray transfer of Al-alloys metal inert-gas (MIG) welding has the advantages of well-adjusting of the length of arc and beautiful appearance of weld due to the characters of droplet transfer. In this study, the self-adapting control which is brought to meet the arc of meso-spray transfer is accessed by analyzing the approximate entropy (ApEn) of the arc voltage on the aspect of non-linear dynamics. Under self-adapting control, the change of ApEn value with the varing metal transfer mode is discussed, which is due to the change of the parameter of process. Under spray transfer, two kinds of ApEn values of the self-adapting control and common pulsed control are compared, and we find that the self-adapting control is fit for meso-spray transfer. The results show that the smaller the value of approximate entropy is, the better the effect of the self-adapting control is.
