The invention relates to a
laser cladding device applied to workpiece repair. The device comprises a cladding platform, clamping equipment, cladding
processing equipment and cladding treatment equipment, wherein the clamping equipment is arranged on the cladding platform, the cladding treatment equipment comprises a travelling mechanism, a heating device and a
powder recovery device, the travelling mechanism comprises first guide rails, a travelling frame and a
moving frame, the two first guide rails are distributed on the two sides of clamping mechanisms correspondingly, the bottoms of the two ends of the travelling frame are arranged on two second guide rails in a sliding mode, the
moving frame is located above the travelling frame, a shear type lifting frame is arranged at the top of the
moving frame, a mounting platform is arranged at the top end of the shear type lifting frame, and the heating device and the
powder recovery device are arranged on the mounting platform. According to the
laser cladding device, the heating device is driven by the travelling mechanism to move in the three-dimensional direction, a heating base is arranged on the outer side of a to-be-cladded position of a workpiece, the workpiece is locally preheated by means of an
infrared heating
pipe, and the cladding quality is effectively guaranteed.
