To provide a device and a method for cladding by welding for a white metal for bearing in which the welding speed is increased by jointly using the arc discharge and the laser beam, the penetration ratio of a welding base metal (iron Fe) is small, and the seizure resistance and the bearing pressure resistance are excellent.
In a cladding by welding device, the cladding by welding is implemented by melting a surface of a bearing base metal by the arc discharge and the laser beam 3, and feeding the white metal alloy for bearing to the molten portion. A laser beam generating means which achieves the weaving orthogonal to the welding advancing direction, has the plume, and forms a molten pool on the surface of the bearing base metal is provided. An arc generating means which is inclined forward in the welding advancing direction with respect to the laser beam, and melts the bearing base metal together with the laser beam to form the molten pool through the plume of the laser beam 3 is provided. A bearing white metal alloy wire feeding means which is inclined backward in the welding advancing direction with respect to the laser beam 3 to feed the white metal alloy wire for bearing to the molten pool is provided.
