The current waveform control process of a developed new type IGBT current waveform controller of CO2 arc welding is simulated in this paper. The simulation results are according to welding technical experiment. The research shows that the simulation system can be used to simulate and test current waveform control parameters, and can make sure the parameter values of waveform control, naturally, these parameters will be corresponding to different welding variables. By means of the simulation system, the influence regularities of waveform control parameters in the CO2 arc welding droplet short-circuiting transfer can be researched and be got. Moreover, the simulation system will also provide a basis that the basic mode of real-time current waveform control can be established.
