“…It makes the "element" with high-speed rotation to penetrate the upper lower-hardness plate, and realizes the friction spot welding with the higher-hard plate such as TFSS. Through the principle of rotating friction melting, completes the welding of the "element" (steel) with the TFSS under the effect of pressure, and form a solid joining [16] [17] [18].…”

Green and low carbon promote the application and development of lightweight materials in body-in-white. Large-scale die-casting Al alloy (DCAA) and high-strength thermo-formed steel sheet (TFSS) have put forward higher requirements for the application of joining technology of high-strength steel/Al dissimilar materials. Taking the new die-casting Al alloy body as an example, this paper systematically studies the progress of the latest joining methods of steel/Al dissimilar material with combination of two-layer plate and three-layer plate. By analyzing the joining technologies such as FSPR, RES, FDS and SPR, the technology and process characteristics of steel/Al dissimilar material joining are studied, and the joining technical feasibility and realization means of different material combination of the body are analyzed. The conditions of material combination, material thickness, material strength, flange height, preformed holes and joint spacing for achieving high-quality joining are given. The FSPR joining technology is developed and tested in order to meet with the joining of parts with DCAA and TFSS, especially for the joining of three-layer plates with them. It finds the method and technical basis for the realization of high quality joining of dissimilar materials, provides the early conditions for the application of large DCAA and TFSS parts in body-in-white, and meets the design requirements of new energy body.

To solve the problems of low strength and unsatisfactory connection quality of clinching in three-layer sheets, a method of clinching aluminum alloy three-layer sheets with an inclined wall die was proposed. AA5052 aluminum alloy sheets were chosen as the research objects. Elastic-plastic finite element simulation and experimental research were conducted to analyze the mechanism of clinching joints in three-layer sheets and a finite element method has been used to investigate and summarize the five stages of forming a three-layer aluminum sheet clinching. Six load distribution methods were designed to investigate the strength of clinching joints in three-layer sheets. The failure mode and failure mechanism of the joints in the shear and peel experiment were comprehensively studied. The comparison between the experimental and finite element results had an error of less than 8%, indicating that the finite element model was highly reliable. The failure strength of the joints and the energy absorption values were determined by physical experiments, and the results show that the D-2 joint has a maximum shear strength of 3400 N and an energy absorption of 6.67 J. The D-3 joint has a shear strength of 3040 N and an energy absorption of 9.29 J. The T joint has a lower strength and a higher failure displacement, with the T-3 joint having a maximum peel strength of 690 N and an energy absorption of 11.876 J.
