SOLUTION: A welding current 4 and an arc voltage 5 are recorded in a recorder 7, and the number N of short-circuits generated per unit time and the number n of instantaneous short-circuits per unit time are counted from the waveform of the arc voltage. The calculation of N is performed a plurality of times while changing the arc voltage at several points. A plurality of droplet transfer stabilization coefficients n / N are compared with each other, and the droplet transfer stabilization coefficient n / N is in a range of 0.4 or less in a low current region indicating a short circuit transfer, and in a high current region which is a globulular transfer.

Description of the Related Art In recent years, welding robots using a CO 2 welding method (carbon dioxide gas arc welding method) have been widely used for manufacturing various welding structures. However, since this CO 2 welding method uses 100% CO 2 as a shielding gas, as shown in FIG. 6, many spatters having different types of generation due to scattering of droplets are generated. Therefore, many post-processing operations are required, such as cleaning and replacing the welding nozzle and removing spatter attached to the vicinity of the welding line.

域などが複雑に関係して異なってくる。That is, due to such a trend, welding power supply manufacturers compete with the conventional thyristor power supply to develop an inverter power supply that generates less spatter.
We have been developing low spatter wires by devising the design of the components of the welding wire, but none of them has been satisfactory.
The amount of spatter generated is determined by a synergistic result of the shielding gas composition, welding conditions, welding power source characteristics, welding wire composition, and the like. The selection of welding conditions with a small amount of spatter in the CO 2 welding method depends on the characteristics of the welding power source to be used, the composition of the welding wire, the diameter of the wire, the welding current region to be used, and the like, and differs in a complicated manner.

囲は異なってくる。In the arc welding method, a droplet transfer form as shown in FIG. 7 is shown depending on the welding method and welding conditions. That is, the droplet transfer mode in CO 2 welding is roughly classified into a low current region → short circuit transition and a high current region → globulular transition. There is an intermediate region between the short-circuit transition region and the globular transition region, and the current range varies depending on the wire diameter used.
