Patent ID: 8664568

Claim:
An arc welding control method of welding by generating an arc between a weld wire and a base material, comprising: carrying out the weld at a welding start period before a steady welding period and at a welding end period after the steady welding period with a welding current and a welding speed different from those at the steady welding period according to a material of the weld wire or a material of the base material, wherein the material of the weld wire or the material of the base material is mainly aluminum, wherein, at the welding start period, the welding current is controlled so as to be higher than a welding current at the steady welding period, and the welding speed is controlled so as to be lower than a welding speed at the steady welding period, and the welding current is controlled to ramp down to the welding current in the steady welding period for at least a portion of the welding start period.
