摘要： PROBLEM TO BE SOLVED: To provide a carbon dioxide gas shielded arc welding method and a welding device, in which sputtering reduces, and a weld quality improves.SOLUTION: A welding device includes: a power supply circuit for applying a voltage across a torch and a base metal, and a power supply control device that controls the voltage of the power supply circuit. The power supply control device controls the power supply circuit such that a high level current is output during a first arc period Ta1 that is an initial period of an arc period that continues after a short period Ts, and an arc current corresponding to a regulated welding voltage is output during a second arc period Ta2 that is the latter period of the arc period. The power supply control device controls the power supply circuit such that a high level current is generated having a waveform increasing and decreasing at a constant frequency and constant amplitude superimposed on the high level current. By superimposing the waveform, the elevation of a droplet caused by a repelled force by the arc can be prevented, allowing the droplet to be formed in stabilization.

In the stationary step, the consumable electrode is made to move to the base material in a state where the movement speed Vv is a stationary speed v4 that is larger than the first speed v1.

摘要： PROBLEM TO BE SOLVED: To maintain a stable welding status even if an electrode minus polarity current ratio in a consumable electrode AC pulse arc welding is set at a large value.SOLUTION: Welding is performed by: carrying the electrode minus polarity base current Ibn less than the critical value during an electrode minus polarity base period Tbn; then carrying the electrode minus polarity peak current Ipn of a value larger than the electrode minus polarity base current Ibn during an electrode minus polarity peak period Tpn; then carrying the electrode plus polarity peak current Ip of a critical value or more during an electrode plus polarity peak period Tp: and then carrying the electrode plus polarity base current Ib less than the critical value during an electrode plus polarity base period Tb. The electrode plus polarity base current Ib has a tendency to become smaller as the absolute value passes over time. The current value in the first half part of Ib becomes large so that arc-off can be suppressed. The current value in the last half part becomes small, so that sputtering is also decreased.
