In laser cladding, high cooling rates outcomes with superior mechanical and metallurgical properties. However, this characteristic along with the additive nature of the process significantly contributes to the formation of the thermal stresses, which are the main cause of any potential delamination and crack formation across the remolten area. To reduce thermal stress caused and better manage the microstructure, a strategy of dynamic local self-preheating is designed. Laser cladding experiments of no preheating, static global preheating, and dynamic local preheating with gray cast iron are conducted. Parallel to experimental investigations, numerical models are established to study the temperature distributions and thermal stresses in different processes. The results indicate that dynamic local self-preheating contributes reducing the transient thermal stress and residual stress compared with others.
