Abstract

67 [Title of Invention] LASER CUTTING AND MACHINING METHOD FOR PLATED STEEL PLATE, LASER CUT-AND-MACHINED PRODUCT, THERMAL CUTTING AND MACHINING METHOD, THERMAL CUT-AND-MACHINED PRODUCT, SURFACE-TREATED STEEL PLATE, LASER CUTTING METHOD, AND LASER MACHINING HEAD 5 A laser cutting and machining method for plated steel plated, when irradiating a laser beam LB on to the upper surface of a plated steel plate W and laser cutting and machining same: a 10 plating layer-containing metal that has been melted and/or evaporated by the irradiation of the laser beam LB is caused to flow on to a cut surface of the plated steel plate W as a result of assist gas that is jetted towards a laser machining units; and the plating layer-containing metal is coated on the 15 cut surface.
