  Laser Cladding is the conventional techniques for metal surface coating to improve corrosion resistance and strength while retaining the properties of the base metal. In this study, Ni base alloy is coated on a carbon steel by using pulse YAG laser. To investigate the degree of fusion between the base metal and the coating material, the depth and width of fusion of the base metal is calculated by using the finite element method for heat conduction. By comparing the calculated results with the experimental result, it is found that the depth and width of fusion can be predicted by the simulation. The depth of fusion increases as the peak power of pulse radiation increases, and is doubled by preheating the base metal from room temperature to 731 K. By increasing the degree of fusion, the adhesiveness between the base metal and coated metal is heightened but the hardness of the clad part is lowered.
