| Abstract: | The surface dents of rolls made with 20 steel was modified by multi-track overlapping with laser cladding feeding power coaxially from the intern hollow space.The results show that,after repairings the shape of roller is resumed,the microstructure and properties of the added material are better than the base and metallurgical bond is obtained in the interface.The residual stress is very small and with little deformation around the surface dents. |
