A new type of parallel arc waveform control method is proposed and implemented, and the corresponding IGBT waveform controller is designed. This method can be used to control the arc waveform during the droplet transfer of CO2 arc welding. The real-time sampling of welding arc parameters and process tests show that the wave controller developed has obvious effect on reducing metal splash and improving weld formation
