Beschreibung
Zusammenfassung:	A hybrid welding device capable of reducing an influence of by-products such as spatters, plasma, plumes, and fume, and reducing contamination of a laser optical system and welding defects is provided. A laser head includes a laser nozzle that forms an optical path of a laser beam, a first rectifying plate that is arranged on a tip side of the laser nozzle so as not to interfere with the laser beam, a first air knife that injects compressed air along the first rectifying plate, a second rectifying plate that is arranged between the first rectifying plate and the welded portion so as not to interfere with the laser beam, and a second air knife that injects compressed air along the second rectifying plate. The first rectifying plate and the second rectifying plate have a shape elongated in a direction perpendicular to an optical axis of the laser beam and a welding direction. The second rectifying plate has a torch opening through which a tip of a welding torch can be inserted.
