Abstract: With the increasingly fierce competition in the commercial vehicle market in recent years, product design optimization, process optimization, etc. have become important measures for cost reduction and efficiency improvement. Applying automation technology to optimize the traditional complex welding and assembly production process of automobiles, improving production efficiency and shortening the product delivery cycle has become a trend in the industry. This paper addresses the complex process of traditional serial number stamping in commercial vehicles, applies lean production value stream technology to identify non-value-added points throughout the entire operation process, and at the same time benchmarks against industry leading enterprises, introducing automatic numbering technology to increase the proportion of value-added operations in the physical flow, reducing six steps such as sign plate processing, transportation and distribution, and improving operation efficiency by 26%, providing feasible technical support and solutions for the optimization of the welding and assembly line process.

Key words: welding assembly; serial number; process optimization; work efficiency
