The evolution of temperature field of the continual motion induction cladding and the depth of heat affected zone are studied in this study. A three-dimensional finite element model for the point type continual induction cladding is established to investigate temperature distributions of fixed and motion induction cladding modes. The novel inductor is designed for cladding of curved surfaces. The modeling reliability is verified by the temperature measurements. The influence of process parameters on the maximum temperature and the generation and transfer of heat are studied. Quantitative calculation is performed to its melting rate to verify the temperature distribution and microstructures. The results show that a good metallurgical bond can be formed between the cladding layer and substrate. The melting rate gradually falls from the top of the cladding layer to the substrate, and the grain size in the substrate gradually rises. The heat affected zone is relatively small compared to integral heating.
