LASER CUTTING METHOD FOR PLATED STEEL SHEET, LASER PROCESSING HEAD AND LASER PROCESSING APPARATUS

Laser cutting on a plated steel sheet is executed by cutting the plated steel sheet by irradiating the plated steel sheet covered with a plate metal with laser light at a wavelength in a 1 micrometer band; and emitting assist gas onto a cut surface of the plated steel sheet, the cut surface being fo...

Zusammenfassung:	Laser cutting on a plated steel sheet is executed by cutting the plated steel sheet by irradiating the plated steel sheet covered with a plate metal with laser light at a wavelength in a 1 micrometer band; and emitting assist gas onto a cut surface of the plated steel sheet, the cut surface being formed in the step of cutting, to make the plate metal fused by irradiation of the laser light flow to the cut surface so as to cover the cut surface with the plate metal.
