ARC-WELDING METHOD AND ARC-WELDING APPARATUS |
| 摘要 |
An arc-welding method in welding by repeating a short circuit and an arc. When the sign of opening of the short circuit is detected, the welding current is reduced from a first current value at the detection of the sign to a second current value, which is lower than the first current value. When the opening of the short circuit is detected, a pulse current having a peak value higher than the first current value is supplied at a plurality of times in the arc period. This suppresses porosities and spatters when galvanized steel sheets are welded. |

1. An arc-welding method in welding by repeating a short circuit and an arc,
the arc-welding method comprising;
when a sign of opening of the short circuit is detected, reducing a welding current from a first current value at the detection of the sign to a second current value, which is lower than the first current value; andwhen the opening of the short circuit is detected, supplying a pulse current having a peak value higher than the first current value at a plurality of times in an arc period. |
