Using the model of local thermodynamic equilibrium(LTE),the electron temperature at 37?mJ/pulse of laser energy was about 15?000?K.
在局部热力学平衡近似下 ,测试得到 :在激光能量为 37mJ/pulse时 ,等离子体电子温度在 150 0 0K附近抖动 ,且随延迟时间无明显变化 ;在激光能量为 6 2mJ/pulse下 ,电子温度上升至 1750 0K附近 ,但随延迟时间有较为明显的波动现象 。
101)×1017cm-3,the voltage output of GMAW source was decreased,and the formation of local thermodynamic equilibrium(LTE) of hybrid welding arc plasma was accelerated.
101)×1017cm-3,降低了GMAW热源输出电压,促进了焊接电弧等离子体局部热力学平衡(LTE)的建立。
