Zusammenfassung:	Laser forming is a thermal process for deformation of sheet metal by thermal stress. In this paper, the technique of laser forming is applied to flatten a protruded distortion on the sheet metal, and the mechanism of flattening is investigated experimentally. The protrusion of some height is intentionally produced by pressing a steel ball on a flat sheet metal. The laser beam was irradiated at the area of distortion, and as a result, the protrusion disappeared and an almost flat sheet metal could be obtained.
