| Abstract: | This article study the factors affect laser welding quality of high strength steel in NC. Based on the analysis of corresponding factors of experiment, experimenting on tensile mechanics property and welding line metallographic and micro-rigidity to welding materials, analyzing the joint with SEM., testing the quality of welding line by salt-water corrosion experiment. And analyzing common quality defects of high strength steel welding line. A series of process parameters which can effectively control the weld quality of High Strength Steel are obtained. |
