Abstract: With the low-carbon transformation of global industrial automobiles, the challenges faced by related connection technologies in the process of body lightweight are increasing. Considering the cost and effect of lightweight, selecting body materials reasonably, matching different connection processes, and providing more ideas for product design stage under the premise of meeting industry quality standards and reducing product weight have become an inevitable trend of lightweight technology development. The rational use of various lightweight materials can effectively reduce the weight of the body and improve the performance of the body.The research progress of several new connection processes for different lightweight materials of the body is systematically summarized. The metallurgical connection technology, mechanical connection technology, bonding technology and composite connection technology are reviewed and analyzed. The research progress of various new processes and their extended processes in recent years is described. The technical principles, connection strength criteria, process advantages, limitations and application status of various processes are analyzed in order to provide useful reference for the design and manufacture of new connection processes for automotive lightweight materials. Protect the body lightweight connection process.
