| Abstract: | This paper describes the process of Nb:YAG laser welding on zinc-coated steel for car body.The weld formation,microstructure and joint strength of the samples under variant laser welding condition was analyzed and evaluated with the method of presetting gap between the sheets.The research results indicate that the influence of vapor from zinking layer during laser welding can be decreased effectively with the presetting gap,thereby the high-quality joint of zinc-coated steel sheet can be obtained. |
