A welding apparatus includes a primary laser generator for emitting a primary laser beam; an arc welding power source; a consumable filler electrode; and at least one secondary laser generator for emitting a secondary laser beam. The primary laser generator, the arc welding power source, and the consumable filler electrode together form a hybrid laser welding system. The secondary laser beam impinges on a weld area before, after, or before and after focusing the hybrid laser welding system at the weld area. A welding method is also provided. |
