Improvement of a Welding Workshop Logistics System Based on Lean Thinking

Lean production is a way to promote production and manage the level of manufacturing as well as to enhance competitiveness in a workshop. Welding is one of the key links of the four important technology processes in auto manufacturing. Based on the theory of lean thinking, this paper took the CS (Changhe) Automobile Company as a specific case and analyzed the current situation of its welding workshop with the SWOT matrix. Conclusions are drawn that enhancement of the logistics system of the welding workshop is necessary. Led by the thought of JIT (just in time) and the balancing of lean production, the basic idea of improving the logistics system is discussed here, and the specific programs for improving the workshop logistics system are put forth. By comparing the improved data, the conclusion shows that the logistics cycle times are cut, site areas are saved, product quality is controlled effectively, labor intensity is significantly reduced, and the production balance in the welding workshop is significantly improved. Thus, the improvement of a welding workshop logistics system based on lean thinking contributes to improving vehicle quality, reducing manufacturing costs, and promoting production efficiency.
