| Abstract: | In order to reduce the staggered joint and improve the quality of rear bottom of the first level fuel tank, the mechanism of the misplacement of circumferential welding and measure are brought forward on the assemble and welding process. It indicates that the quality of the circumferential misplacement of the rear bottom could be improved obviously after application the process in production. |
