Abstract
A method of overlaying by a laser beam, comprises the steps of: relatively moving and irradiating a laser beam with respect to a base metal and simultaneously putting an other metal material than the base metal material on the base metal surface; and forming an overlay layer by melting the other metal material, wherein the overlay operation is performed in such a manner that an inclined angle .theta. with respect to the base metal surface of the beginning end portion surface becomes a range of 8.degree.<.theta.<27.degree..
