Body in-white （BIW） welding precision plays a decisive role in the assembly effect and performance. To effectively control the BIW welding precision will guarantee the body quality. The main deviation results from the tolerance accumulation of each part. Therefore, controlling body deviation is mainly by controlling the precision of jigs, fixture, mold the precision so as to control the tolerance accumulation. If the matching accuracy is higher than the prescribed value, it will affect the automobile manufacturing quality, production cycle and product cost. Improving the quality of BIW will enhance the market competitiveness of products.
