Abstract

This work presents the thermal field computation of a wire getting a laser supported material cladding. We present two complementary models, based on finite volume approaches. First, we present a one dimensional model in which moving of the wire is integrated by mean of an advection term in the heat diffusion equation. It gives the mean temperature variation along the wire An analytical solution of this problem is also given. Secondly, a three-dimensional model gives the complete thermal field. These two models are confronted with experiments. The result of the first one is compared to a maximum mean temperature measuring. The second is validated by comparison with microphotography of the melted zone, and in-section micro-hardness measurements.
