In the article, the principle of narrow lap welding and judgment methods for weld quality are clear and definite as well as the hardness impact of various martensite during rapid cooling for strip steel of this material and the CCT diagram of rapid cooling phase transformation for carbon steel are analyzed. The obtained drawing test results of weld are qualified and the fracture is not at weld in tensile test through adjusting welding parameters as well as increasing annealing process of weld so that the quality of weld seam is eligible in actual production.
