Abstract： The application of new technology is one of the important means of lightweight. In this paper， the forming technology and application of integrated thermoforming laser welding door ring in a certain model are briefly described， and the strength of the door ring is checked. The hot forming laser welding technology is used in the forming of door ring， which saves the cost of design and die reduces the energy consumption of production， and realizes lightweight， and the weight loss of door ring is over 10%.
