Table 1 Classification criteria and characteristics of laser weld points.
ID | Weld point type | Classification criteria and characteristics description |
|---|---|---|
0 | good | Indicates a well-formed laser weld point. |
1 | guBao | Refers to the presence of a significant bulge in the laser weld point. |
2 | xuHan | Represents incomplete welding that has not yet resulted in a break. |
3 | duanLie | Clearly indicates a fracture. |
4 | shuangLuoXuan | Occurs when a laser weld point is re-welded twice, causing overlap. |
5 | hanChuan | Indicates the presence of holes within the laser weld point. |
6 | wuNengLiang | The area around the laser weld point appears dark and lacks colour information. |
7 | shaoHanDian | A condition where there is insufficient solder or welding pressure, resulting in blank areas on the board or only faint welding traces. |
8 | jiaJiao | The presence of noticeable foreign black contaminants on the welded board. |
9 | shaoJiao | Burnt phenomena occurring during plastic joining due to high temperatures. |
