Dissimilar joining of aluminum and steel is one of the fundamental techniques for achieving weight reduction in the automotive industry. Self-piercing rivets have been widely adopted for the aluminum-steel lap joint because of its simplicity and high joining strength. In this study, the joining quality of the aluminum-steel joint produced by self-piercing rivets is investigated depending on the strength and thickness of the aluminum sheet. Four different tensile strengths (228, 305, 320, and 326 MPa) of aluminum are considered in this study, which corresponds to Al5052-H32, Al5754-H18, Al5083-H32 and Al6061-T6. For the thickness variation test, Al5052-H32 sheets with a thickness of 1.2, 1.5, 2.0, 2.5 mm are used. The SPR joint quality was quantified with cross-sectional visual analysis and tensile lap shear test. In aluminum(top)-steel (bottom) SPR joint, it was observed that the joint load increased with increasing aluminum strength up to 320 MPa. Nevertheless, the thickness of top aluminum was found to not affect the joint strength between the thickness of 1.5 ~ 2.5 mm. In steel(top)-aluminum(bottom) SPR joint, it was found that joint strength did not change with aluminum strength but increased with increasing aluminum thickness.

The objective of this study is to compare the strength of riveted joints fabricated by traditional riveting (with pre-drilled holes) and self-piercing riveting (SPR) for different types of joints. Riveted joints were produced using steel and aluminum alloy rivets and two types of sheet material: 235JR steel sheet and EN AW 6060 aluminum alloy sheet with the following dimensions: length l = 100 ± 1 mm, width b = 50 ± 1 mm and thickness g = 2 mm. For all tested types of riveted joints (pre-drilled and SPR), 5 sets of joints were fabricated, each set containing 6 samples. The sets of joints differed with respect to the number of rivets (1, 2, 3, 4 and 6 rivets), joint type (single-, three- and four-riveted joints) and lap length. For all tested joints, the highest load capacity was obtained for self-pierced riveted joints, while the lowest - for pre-drilled joints with aluminum alloy rivets. In addition, it was found that the shear strength of self-pierced riveted joints is higher than that of aluminum and steel blind rivets.
