摘要
In an arc welding method of performing welding by employing CO 2 gas as shield gas, supplying a welding current to flow between a welding wire and a workpiece to be welded while feeding the welding wire toward the workpiece, and generating an arc with the welding current, the arc welding method includes a welding step of performing the welding of the workpiece while executing control to adjust the welding current, and a welding termination step of executing control to apply the welding current having a trapezoidal waveform when the welding of the workpiece is terminated.
