Abstract: Self-piercing riveting is a new connection technology emerged in recent years with excellent performance, green and high efficiency. It can connect the same, dissimilar and multi-layer sheets, and is expected to become the key technology for the connection of aviation light alloy sheet materials. Taking 2A12 (group A) and 6061 (group B) heterogeneous self-piercing riveted joints as the research objects, the static performance test and failure microscopic analysis were carried out, and the forming quality, mechanical properties, failure mode and failure mechanism of the joints were systematically analyzed.The results show that the SBA (6061-2A12) joint has the best forming quality, the SBB(6061-6061) joint has the best sealing performance, and the SAA (2A12-2A12) joint has the best symmetry. The SAA joint has the strongest static load strength, the SBB joint has the best shock absorption capacity, and the SBA and SAB joints have good comprehensive mechanical properties; the failure modes of SBB joints are all pull-out failures; the failure modes of SAA(2A12-6061) joints are the most unstable, and three different failure modes appear; the main failure mode of joints is pull-out.
