Abstract： With the development of modern automobile technology and customers' pursuit of personalized automobile products， the number of body-in-white（BIW） models is increasing. Co-production with different models and configurations has become a trend of automobile production line. The wrong assembly， missing assembly and missing welding of parts have become major factors affecting the quality of BIW. In this paper， a new type of pneumatic error prevention device is designed to prevent missed welding and wrong welding of body-in-white， so as to ensure the quality of solder joints of body-in-white.

Keywords： body manufacturing; missed welding; solder joint; pneumatic error prevention device

一台白车身总成由上百个钣金零件逐级焊接而成，焊点数量在3 000～5 000点之间，电阻点焊和CO2保护焊是车身零件连接的主要方式，其中电阻点焊占总焊点数的90%。（剩余3118字）
