【Abstract】 The interaction of laser beam with the target materials is a complex, multi-dimensional, multi-parametric phenomenon. Numerous studies have been performed in the past decades by using either analytical or numerical approaches, or both combined. In this paper, the state-of-the-art of the research on modeling of deep penetration laser welding is reviewed. Some different types of mathematical models are introduced, as well as the modeling methods are discussed.更多还原
