| Abstract: | Skeleton spot welding is an important process of manufacturing PWR fuel assembly . In AFA 3G Skeleton spot welding, the pressure resistant spot welding technology of grid and variable thickness guide thimble is a new technical problem. By means of a lot of experiments, it is discussed in detail how different welding parameters impact on weld quality. Welding parameters impact on welding spots tensile force, welding spots diameter and welding spots corrosion performance. Analyzing and comparing with test data can get better welding parameters. |
