Laser cladding and detection equipment applicable to surface of hydroelectric power station unit runner chamber and operation method

The invention discloses laser cladding and detection equipment applicable to the surface of a hydroelectric power station unit runner chamber and an operation method. The laser cladding and detectionequipment comprises a flanged annular railway assembly; the flanged annular railway assembly is annularly arranged in the hydroelectric power station unit runner chamber; a moving trolley is placed onthe flanged annular railway assembly; an industrial manipulator is arranged on the moving trolley; and laser cladding equipment and detection equipment are arranged at the tail end of the industrialmanipulator. The laser cladding and detection equipment can be used for repairing work of the hydroelectric power station unit runner chamber, the mechanical property of a cladding layer on the surface of a steel plate of the hydroelectric power station unit runner chamber is further improved, the thermal deformation of the cladding layer is reduced, the thickness and surface accuracy of the cladding layer can be accurately
