| 摘 要： | We study the effects of welding speed,Marangoni convection and natural convection on heat transfer and melt flow in a laser full-penetration welding using a three-dimensional modelling approach.The computed results demonstrate the importance of considering Marangoni convection.The predicted weld pool profile is favourably compared with experimental observation.
