摘要：
One of the methods of getting better CO2 arc welding technology performance and decreasing spatter efficiently is improving the arc welding power source and controlling the behavior of arc and droplet transfer. According to the reasonable instantaneous electric current characteristic of short-circuiting transfer, the AWP (Adapting Welding Physics Process) waveform control thought of CO2 short-circuiting transfer is put forward in this paper. A simulation study is made and a simulation waveform is obtained. The experimental system is set up and a great number of data is carried out. The result of simulation is suitable for that of experiment on the whole. It shows that the simulation model is rational and practicable.
