| 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,从而探讨了高频脉冲TIG焊电弧的高频效应机理。实验研究表明高频脉冲TIG焊电弧阳极能量密度高于直流电弧,小电流时高频效应显著,适宜焊接精密超薄件,推荐脉冲频率为20kHz。

| Abstract: | The distribution of the anode average current density and the dynamic process of the high frequency pulsed TIG welding arc are determined first time in this paper. Their mathematical models are establlished, and the comperession mechanism of high frequency pulsed TIG welding is explored. Experiment have show that the anode current density of high frequency pulsed TIG welding arc is higher than that of direct arc, specially during the welding current is low. The high frequency pulsed TIG welding is a good technic to be used for welding precise super-thin plates and here we recommend an adaptive pulse frequency about 20kHz. |
