Abstract
In a laser processing method, laser lights of fiber lasers or direct diode lasers is irradiated onto an iron-based plate material from a nozzle, a nozzle with a nozzle opening whose opening diameter is preliminarily set according to a thickness of the plate material is selected from plural nozzles whose nozzle openings have different opening diameters from each other, and the plate material is cut while irradiating the laser lights onto the plate material and injecting assist gas from the nozzle opening toward the plate material.
