By understanding the principle and charac-teristics of arc brazing,we can determine the process plan for arc brazing of aluminized zinc and stainless steel plates. The welding power source and welding wire are selected according to the base material. The welding parameters of the aluminized zinc plate are determined through process tests and metall-ographic analysis. Arc brazing achieves a direct welding con-nection between dissimilar metal,especially for galvanized,tinned,aluminized zinc plates and other coatings. It can ensure the corrosion-resistant capabilities after welding, and would be significant for the popularization and application upon pro-duction design.
