| Abstract: |
| Friction stir welding is a novel solid-state welding technology, which provides a new joining method for light alloys such as aluminum alloys. Research findings including the basic characteristics of friction stir lap welding (FSLW) joints, the law of material flow and the optimization of tool geometry have been summarized. And the prospect of optimization of tool geometry in FSLW is provided. |
| Key words: friction stir lap welding aluminum alloy the law of material flow the optimization of tools geometry |
