Abstract:
A laser surface treatment method for treating a surface of a workpiece having an irregular shape includes radiating a laser so that the surface of the workpiece which is placed in a direction forming an acute angle with respect to the laser becomes an untreated plane. The method also includes scanning with the laser so that the surface of the workpiece which is placed in the direction forming an acute angle with respect to the laser becomes an untreated plane.
