In the automotive industry, more efforts are put to promote the stability of structure while reducing the weight of the vehicle. The application of laser tailor welded blanks is one of the most successful new technologies to be used. Due to its obvious advantages, laser tailor welded technology is widely used in the structure parts of body-in-white. Laser tailor welded inner doors are applied in the new car models of domestic automobile manufactures because of their obvious weight reducing advantages. The structure of inner doors belongs to the typical cover parts and is very complex in its shape. In this paper, the typical characters of laser tailor welded inner doors are extracted. Finite element analysis model of stamping process for tailor welded inner doors are established. By means of finite element analysis and practical stamping, the behavior of laser tailor welded inner doors in stamping process is studied. Simulation and practical stamping results show that the laser welded seam has the obvious movement for the laser tailor welded inner doors during the stamping process.
