Laser cladding is a novel advanced surface processing technology developed in recent years. The technologies of laser cladding surface modification has the characteristics such as capable of processing complex components with better microstructure and properties of cladding layer, wider applied category of processing materials. Therefore,it can be widely used in the repairing of complex components and has an extensive application prospect. However, cracking are still the ur- gent problems yet to be further broken through. The principle, characteristics and application of laser cladding forming were introduced. The problems existing in this technology were proposed and the development direction of this technology was prospected and predicted.
