摘要: Laser keyhole welding is a complicated multi-phases, multi-physics process, especially when assisting gases are involved. A three-dimensional transient model is developed to investigate the dynamics of keyhole, together with the vapour plume and molten pool, in a self-consistent manner. The model features the utilization of sharp interface method for accurate consideration of the complex surface phenomena on the keyhole wall and a comprehensive hydrodynamic calculation for both the vapour plume and molten pool. The …
