Abstract: A plurality of scaly beads is formed and arranged continuously on a base material in welding cycle C that is a sum of arc ON period A during which welding current I flows to a welding wire and arc OFF period B during which welding current I does not flow to the welding wire. This arc welding control method includes: an initial condition setting step of setting initial values of welding conditions for arc-welding the base material; and a scaly bead formation step of forming the plurality of scaly beads in a predetermined welding section of the base material while moving the welding wire at welding speed Vw in the predetermined welding section of the base material. The welding conditions include arc ON period A and arc OFF period B, and further include at least one of welding current I, welding speed Vw, and interval G of the beads. The arc welding control method further includes a welding condition change step of determining whether there is necessity to change the initial value based on a predetermined finish condition for the scaly beads and changing at least one of a plurality of welding parameters to satisfy the predetermined finish condition.
