| Abstract: |
| Equiaxial area in solidified nugget structure can be extended by incubating process,and the nugget with single equiaxial structure can be acquived under appropriate technological condition.Meanwhile, systematic comparison of the mechanical properties of the spot welding joints before and after inacubating process was carried out. |
| Key words: spot welding solidified structure incubating process |
