Abstract

This paper investigates the MPI hot stamping technology for body lightweighting, focusing on the formability of hot stamping materials and processes for laser welded plates of high-strength steel. This technology plays a key role in car body manufacturing, especially in the production of body-in-white, and is of great significance for the material selection and the combination of specification of spliced plates for components such as door rings, as well as for the stable manufacturing process. The study investigates the mechanical properties of laser welded plates in the hot stamping process, and determines the formability of welded plates through the study of the mechanical properties of different types of welded plates. Taking the testing and analysis of the hot stamping properties of double door rings of laser welded plates integrated with multiple components as an example, the method of sampling weld seams of welded plates and the adaptability of this method to be used as an assessment of the formability of welded plates are described. The in-depth testing and study of the mechanical properties of the laser welded plate to assess the formability of the welded plate is intended to provide guidance and reference for the optimization of the hot stamping process and the improvement of production quality and efficiency.
