| Abstract: | This paper analyzes the ultra-poor region of welding point in the process of BIW welding. By using principal component analysis and the data from CMM measurement, the number of error factors can be determined, and the volume to adjust error in welding point can be separated. By analyzing the error resources in the actual welding process and referring to the volume to adjust, amendment is made. With the case study of CMM measurement data from ultra-poor region in the right near light assembly point, it shows that principal component analysis is effective in error control for BIW welding. |
