Modeling and Simulation of a Laser Deposition Process
Abstract
A laser deposition process involves the supply of metallic powders into a laser-heated spot where the powder is melted and forms a melt puddle which quickly solidifies into a bead. In order to design an effective system, the laser beam, the powder beam, and their interactions need to be fully understood. In this paper, the laser-material interaction within the melt pool is reported using a multi-scale model: a macroscopic model to model mass, heat, and momentum transfer. Experiments were also conducted to validate the simulation model.
