Power supplies for gas shielded arc welding with high control speed are being increasingly investigated for improving the welding quality and reduce spatter. In this study, the effect of current change on droplet behavior was evaluated, when high-speed current control is performed at a control frequency of 300kHz through the application of an interleaved back converter to the welding power supply. Consequently, it was confirmed that spatter can be reduced by controlling the current at a high speed.
