Viggiani., 2000, Numerical simulation of the heat penetration in two-plate arc welding, http://nur.nu.edu.kz/handle/123456789/842http://nur.nu.edu.kz/handle/123456789/842A mathematical model and numerical simulation of the three-dimensional and transient metal arc-welding process is presented. The heat source is considered as spatially distributed following a centered Gaussian bell, while the substract material (Al 6063) is assumed homogeneous and isotropic with temperature-dependent thermal properties. Radiation and convection are also calculated through an empirical temperature dependent correlation. Phase-change phenomenon is included as a discontinuity in the material specific heat. Calculations were performed by using a finite volume code (CFX4.2TM). Computed heat penetration and weld metal area are found to be in good agreement with experimental data.enResearch Subject Categories::TECHNOLOGY::Engineering mechanicsmechanical engineeringArticle
