ARC WELDING CONTROL METHOD |
摘要 |
There is provided an arc welding control method. As to a feeding rate of a welding wire, a forward feeding period and a reverse feeding period are alternated cyclically to generate short-circuiting periods and arc periods. When a constriction of a droplet formed at the welding wire is detected during the short-circuiting period, a welding current is reduced to shift to the arc period. Sensitivity of the detection of constriction is changed according to a waveform parameter of the feeding rate. |

1. An arc welding control method of alternating a forward feeding period and a reverse feeding period cyclically as to a feeding rate of a welding wire to generate short-circuiting periods and arc periods in a manner that shifting to the arc period is performed by reducing a welding current when a constriction of a droplet formed at the welding wire is detected during the short-circuiting period, the arc welding control method comprising: changing sensitivity of the detection of constriction according to a waveform parameter of the feeding rate. |
