- Abstract
The physical mathematic model for heat transfer and convection in laser molten pool established. 3D-computer simulation of temperature and fluid fields has been completed with finite difference method. It is shown that in laser molten pool there is a strong fluid flow, which is symmetrical in XY plane and anti symmetric in XZ plane. Due to effects of convection and heat transfer laser molten pool is widen. Surface tension gradient is the main drawing force for convection.
