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 Tabl., 8 Fig.
