Research on Energy-saving Technology of Four Workshops in Vehicle Manufacturing Enterprises

Four technology workshops in automotive industry （welding, painting, assembling and pressing） consume large amount of energy, especially for vehicle manufacturers. This paper introduces the energy-saving technologies of the four workshops in detail, and the research results can be taken as reference. The paper also indicates that while attaching great attention to energy conservation and rational utilization, we should adopt various effective measures to improve vehicle energy efficiency of manufacturing enterprises so that we can bring the limited energy into the full play and lay a solid material foundation for the development of national economy.
