<p>PROBLEM TO BE SOLVED: To provide a laser processing nozzle equipped with an integrated laser beam deflecting device by a simple mechanism. SOLUTION: By this laser processing nozzle, laser lights are condensed so as to perform processing of steel such as welding, boring, and cutting. In this case, a transparent plate 1 equipped with an impeller 6 on a peripheral part is arranged on a laser optical path inside the nozzle, and the impeller 6 is rotated by utilizing air pressure of assist gas 5 discharged in a direction coaxial with the laser light. Thereby, the transparent plate 1 can rotate so that the laser optical path can be shifted.</p> |
