| Abstract: | Laser welding is a widely used laser processing technology,in which the deep penetration welding ratio of laser deep penetration welding can reach 2:1 in sheet metal welding,and the strength and stability are superior to traditional welding.In this paper,YAG laser is used to make a welding experiment on 0Gr18Ni9 with the thickness of 2mm,the welding penetration and width are measured,the parameter optimization is carried out by orthogonal experiment method,the impact of the laser parameters on welding seam is analyzed,the hardness of welding joints is analyzed by microhardness testing,which provides a reliable basis for the selection of laser welding process parameters. |
