Notes:
Arc brazing technology for joining has been recently developed. Because of itsadvantages, it has been used more and more frequently in the automobile industry, and thistechnology is widely used in practical joining applications. Many welding researchers have paidmore and more attentions in this field. Based on the experimental analysis of CuSi3 filler metalspreading, wetting behavior on galvanized steel sheet and its interfacial microstructure in tungsteninert gas (TIG) arc brazing process, the governing equations and boundary conditions of filler metaldroplets under the actions of gravitational force, surface tension and arc pressure force is conducted,then they have been transformed into finite volume equations, The flow behavior at different arcingtime in filler metal droplet was calculated by PHOENICS code using SIMPLEST algorithm. It canbe concluded that the flow adjacent to the surface controls the final droplet profile, and the fluidflow does great contribution to the whisker-like intermetallic compound fragmentation behavior dueto its stirring force at the interface. The simulation is useful to interpret the free surface evolvingbehavior and the final profile of filler metal droplet in arc brazing, it also provide a new idea aboutthe interface growth behavior study and offer a practical guide in production
