Laser clad layer forming method and laser cladding device

The invention provides a laser clad layer forming method and a laser cladding device. A laser clad layer forming method includes a partitioning process of partitioning a formation-scheduled portion for a laser clad layer on a peripheral surface of a workpiece into areas; a phase determining process of holding the workpiece such that an axial direction thereof is horizontal and determining a phaseof the workpiece such that a direction of a normal to the peripheral surface of the workpiece in one area is within a predetermined angle range with respect to a vertical upward direction; and a forming process of irradiating a powder with a laser beam while supplying the powder to the one area in a state in which the phase of the workpiece is determined and melting the powder to form a bead. Thelaser clad layer is formed by repeating the phase determining process and the forming process on the areas to form the beads in the whole formation-scheduled portion. 提供了激光熔覆层形成方法和激光熔覆装置。激光熔覆层形成方法包括：分割处理，其将工件的周表面上的用于激光熔覆层的预定形成
