Abstract
The Marangoni effect caused by surface tension gradient is modeled. The resulting convection flow in the melt pool is demonstrated with different values of the Marangoni coefficient. Its influence on the temperature distribution, the shape of melt pool and thus the shape of solidified track is presented. The role of Marangoni convection on the stability of melt pool and the surface quality of the final track are also discussed.
