| 发明名称 | Hybrid welding method and hybrid welding apparatus | ||
| 摘要 | Disclosed is a method for hybrid welding in which a laser beam is applied to the welding position of objects to be welded, and at the same time, a first wire is fed to the welding position so as to perform arc welding using an arc generated between the objects to be welded and the first wire. In this method, one or more second wires are fed to a molten weld pool formed by the laser beam and arc welding, thereby increasing the amount of welding without increasing the arc current. | ||

| 主权项 | 1. A method for hybrid welding, the method comprising: applying a laser beam to a welding position of objects to be welded so as to perform a laser welding, and simultaneously feeding a first wire with a first deposition rate to the welding position so as to perform an arc welding using an arc generated between the objects to be welded and the first wire according to a first arc current; feeding a second wire with a second deposition rate to a molten weld pool formed in the welding position by the laser welding and the arc welding without performing arc welding using an arc, and having no arc current on the second wire, wherein the objects to be welded, the first wire, and the second wire are made of an aluminum alloy. | ||
