摘要
研制了一种以80C196KC16位单片机为核心,采用U-I模式控制的逆变熔化极脉冲气体保护焊机。通过采集焊接过程中的电弧电压和电流信号,在峰值期间保持电压恒定,在基值期间保持电流恒定,脉冲参数依据一个脉冲过渡一个熔滴的原则选取。在焊接过程中脉冲频率保持不变,通过峰值电流的变化来实现弧长调节。结果表明,该系统工作稳定,焊机具有良好的焊接工艺性能。
The U-I mode inverter P-MAG welding machine controlled by 80C196KC 16-bit single chip computer was designed. By sampling the voltage and current of arc in the welding process, the arc voltage is kept constant in the peak period and welding current is kept constant in the base period. Arc length self-adjustment was realized by changing of the peak current, and the pulse parameter was optimized to make sure the one pulse one droplet transfer mode. The experimental result indicated that the welding machine has perfect welding performance.
