- the initial control time 106 is obtained in advance by experiments or the like.
- the arc control unit 13 controls the output voltage VL.
- the arc period 102 is longer than that when the arc length is appropriate as shown in FIG. It becomes longer, the occurrence of short circuit is delayed, and the average output voltage becomes higher. If the occurrence of a short circuit is delayed, the melting of the wire is promoted, so that it takes time for the molten droplet at the tip of the molten wire to move to the base material, so that the next short circuit time becomes long. Therefore, the current value 104b immediately before opening the short circuit is higher than the current value 104a immediately before opening the short circuit.

- This current value differs depending on the set current, set voltage, wire feed speed, shield gas type, wire type, wire diameter, welding method, and the like, and can be obtained by various experiments and setting unit 9. Since the arc initial current 105d is controlled according to the difference between the set voltage and the average output voltage, it is not related to the current 104b immediately before the short-circuit opening, which is the current immediately before the short-circuit opening.
- the arc initial current 105b which is always higher than the current 104b immediately before the short circuit opening 104b in the conventional control, is delayed in this embodiment and the average output voltage is increased. 2 becomes lower than the set voltage, the arc initial current 105d is lower than the current 104b immediately before the short circuit is opened, as shown in FIG. Thereby, since the welding output in the period after the arc initial current 105d in the arc period 102 can also be lowered, the average output voltage can be set to the set voltage at an early stage.
- the amount of wire melting can be suppressed, the arc length can be shortened, the short-circuit cycle can be shortened, and heat input can be reduced. Then, the bead width can be made uniform, the occurrence of burn-out during gap welding can be suppressed, and the applicable range can be expanded with respect to the occurrence of disturbance and gap welding.
- FIG. 3 is a diagram showing a welding output voltage waveform VS and a welding output current waveform IS when the arc length in the arc welding apparatus of the present embodiment is shorter than an appropriate length during normal welding.
- FIG. 3 shows a case where the arc length becomes shorter than an appropriate length at timing 109 and the arc period 102 becomes shorter.
- the horizontal axis indicates the elapsed time
- the vertical axis indicates the welding output voltage VS and the welding output current IS.
- the arc period 102 is shortened, the occurrence of a short circuit is accelerated, and the average output voltage is lowered.
- the occurrence of a short circuit is accelerated, a short circuit occurs in a state where the melted portion at the tip of the wire is small, so that the time until the droplet at the tip of the wire moves to the base material is shortened. Therefore, the next short circuit time is shortened. Therefore, as shown in FIG. 3, the current value 104d immediately before the short circuit opening, which is the current value immediately before the short circuit opening, is lower than the current value 104a immediately before the short circuit opening.
- the welding output current calculation unit 12 a of the arc initial control unit 12 sets a predetermined magnification (coefficient) greater than 1 according to the difference between the set voltage and the average output voltage at the setting unit 9.
- a predetermined current value I set in advance is multiplied to obtain an arc initial current 105e larger than the predetermined current value.
- the arc initial control unit 12 performs current control such that an arc initial current 105e larger than the predetermined current value I flows during the initial control time 106.
- the predetermined current value I described above is obtained when the arc length is longer than the appropriate length in FIG. 2, the occurrence of a short circuit is delayed, the average output voltage is increased, and the average output voltage is higher than the set voltage. This is the same as the predetermined current value I described as the control.
- the arc initial current 105d is 190A and 105e is 210A with respect to 200A which is an example of the predetermined current value I set in advance.
- magnifications and preset predetermined values of the arc initial currents 105d and 105e are set current, set voltage, wire feed speed, shield gas type, wire type, wire diameter,
- the setting unit 9 sets the value based on at least one of the welding method and the like.
- the current immediately after the short circuit is opened is controlled to be a predetermined current value I.
- the average output voltage is repeatedly calculated every predetermined time T, but the average output voltage compared with the set voltage is a value immediately before being calculated at the timing when the arc initial control unit 12 performs current control, That is, it is the latest being calculated.
- the present invention can expand the range of application to disturbance welding when the arc length changes and gap welding, and can improve the productivity of welding work. Therefore, the arc welding control method and arc welding are mainly used in welding that causes a short circuit. Industrially useful as a device.
