In order to solve the remanufacturing and repairing of universal joint in agricultural vehicles against surface peeling and evident indentation, laser cladding technology was applied to prepare Fe 314 alloy cladding layer on the journal surface of the universal joint. Metallographic structure of the cladding layer was observed with metalloscope and its hardness was tested by Vickers hardness tester. Moreover, a finite element model of the universal joint load in agricultural vehicles was established. After load and boundary constraint were applied, the cloud chart of displacement changes before and after the cladding was concluded. The universal joint repaired through laser cladding was installed onto agricultural vehicles, presenting no surface peeling and cracking more than eight months later. Test results demonstrated that the cladding layer combines with the substrate well and the hardness of the universal joint improves from 170HV0.025 to 560HV0.025. Abrasive resistance of the cladding position is improved significantly and the displacement decreases by 10.8% compared to that before cladding. Laser cladding could improve performances of the universal joint and prolong its service life.
