PURPOSE:To eliminate such a defect as a cracking, etc., prevent ruggedness after scarfing the surface and obtain a smooth surface by irradiating a defective part with a laser beam, and blowing oxygen gas or mixed gas containing oxygen thereto, in a device for eliminating a cracking, etc., existing on the surface of a material such as iron and steel, a non-ferrous metal, etc., by a scarf processing. CONSTITUTION:This working head is provided with optical mirrors 2, 3 for shaping a laser beam 1 emitted from a laser transmitter to a sheet-like beam, a nozzle 8 having an opening whose width is larger than that of the sheet-like beam for blowing oxygen gas, etc., supplied from a gas supply device to the surface of a non-working material 4. |
