高频脉冲TIG焊电弧的阳极行为

Anode behaviour of high frequency pulse TIG welding arc

  • 摘要: 本文首次测定了高频脉冲TIG焊电弧阳极的平均电流密度分布及其中心电流密度动态过程,研究其变化规律并建立了数学模型,从而探明了高频脉冲TIG焊电弧的高频压缩机理.本文还利用自制的微压测试装置,研究了高频脉冲TIG焊电弧阳极轴向压力的分布,建立了数学模型.试验研究表明,高频脉冲TIG焊电弧阳极能量密度高,阳极轴向压力适中,适宜焊接精密超薄结构,推荐脉冲频率为20KHZ左右.

     

    Abstract: The distribution of high frequency pulse TIG welding arc anode average current density and the dynamic process of the said arc anode are determined in this paper. Their mathematical models are established, and the compression mechanism of high frequency pulse TIG welding is explored. The distribution of high frequency pulse TIG welding arc anode axial pressure has been studied by a self-made micro-pressure measuring device. And the related mathematical model is established as well. Experiments have shown that high frequency pulse TIG welding is a useful technique for welding precise super-thin plates. An adaptive pulse frequency of about 20kHz is recommended.
