Beschreibung
Zusammenfassung:	A welding apparatus includes: a laser beam irradiation section that emits a laser beam; a spectroscopic apparatus that receives plasma emission from a molten pool formed by laser beam irradiation, and acquires optical spectral information; and an estimation section that estimates material components of a weld zone on the basis of the optical spectral information, and estimates a property of the weld zone on the basis of the material components.
