Abstract :
Multilayer laser cladding process for the material properties of low carbon steel 1015 for workpiece and nickel alloy with 1.5 wt.% and 3 wt.% nano CeO2 as the powder particles is modeled. Finite Element Method (FEM) solutions of transient heat transfer and mass transfer equations in laser cladding process are presented. Geometry of the deposited material as well as temperature and thermal stress fields across the process area are calculated.
