Effects of Standoff Distance on Magnetic Pulse Welded Joints Between Aluminum and Steel Elements in Automobile Body

Materials Science and Technology

2023

To explore the failure principle of single-point butt clinched joints, the AA5052 and AA6061 sheets were employed to produce the single-point butt clinched joints. The microscopic morphology of the fracture surface, geometrical parameters, static strength, energy absorption and failure details of the joints were analysed. The experimental results showed that fracture forms of sheet materials are the same as ductile fracture. The sheet combination has a significant influence on the mechanical properties of the single-point butt clinched joint, which is ultimately due to the different mechanical properties of the basal sheets. The single-point butt clinching process proposed in this work contributes to simplifying the clinching process while increasing the joining efficiency.

Joining three aluminium alloy sheets by square clinching process

The joining of three-layer AL5052-H32 sheets with the square and round clinching process was studied by experimental means. Two 1.5 mm thick and one 2 mm thick AL5052-H32 sheets with three sheet sequences were joined by the square and round clinching process, respectively. The results showed that the square tools can successfully join three sheets in all three sheet orders, while the round tools can effectively connect three sheets only when the thick sheet is at the bottom. Moreover, the strength of the round joints is generally lower than that of the square joints. The square three-layer joint with the thick top sheet achieves high strength at both two mechanical interlocks.

Experimental investigation of high impact polystyrene/metal self‐piercing riveted joint

Polymers for Advanced Techs

2022

Self-piercing riveting was adopted to join high impact polystyrene (HIPS) and metal sheets which had huge difference in material properties. Three kinds of metal sheet (AA1060, AA5052, and HC340LA) were joined to HIPS sheet. The effect of polymer sheet thickness on mechanical properties of joints was investigated. The static loads of joints were measured in tensile and shearing tests. The failure modes of joints were analyzed. The cross sections of joints were observed by metallographic microscope. Results showed that self-piercing riveting could effectively join HIPS and metal sheets when polymer sheet was placed as top sheet. All joints failed in the manner of polymer fracture in both tensile and shearing tests. For joints with different sheet material combinations, though the cross sections and geometrical parameters of joints had great difference, the static loads and absorbed energy values of joints were nearly the same. When AA5052 sheets were joined to HIPS sheets with different thickness values, with the increase of polymer sheet thickness, the flaring degree of rivet decreased, while static loads and absorbed energy values of joints increased. This was because the strength of interlock structure was higher than that of polymer sheet and the strength of joint was determined by the strength of polymer sheet.
