Consumable electrode gas shielded arc welding method and apparatus |
| 摘要 |
A gas having an arc current-voltage property that is different from a shielding gas is intermittently added to the shielding gas, an arc current is intermittently changed in proportion to an intermittent chemical composition change of the shielding gas at an arc generation region, and an arc generation point situated at a tip of a welding wire is displaced upwardly or downwardly along a groove of a base metal.
