The brazing temperature field of Zincplating steel sheet is modeled by finite element analysis in this paper.Through changing brazing parameters,the changing curves of both 692K (temperature link of Zinc melted) and 1 323K(temperature link of brazing filler melted) are obtained. Compared with the practical experiment results,they are similar. So the brazing parameters can be made with numerical modeling.And it's worth of developing to optimize the brazing process through finite element analysis.
