Abstract
In this work we considered two software tools for the purpose of multiphysics simulation of physical phenomena in weld pool: COMSOL Multiphysics and in-hose finite element (FE) code implemented in Wolfram Mathematica. For validation purpose, two test problems dealing with Marangoni induced convection are solved. Good agreement between benchmark solutions and obtained results is observed. Developed numerical algorithms and computer code can readily be employed for multiphysics simulation in welding. 14 Ref., 1 Table, 8 Figures.
Keywords: marangoni convection, weld pool shape, mathematical modelling, laser beam welding
