ABSTRACT

The welded joint is one of the connections widely used in aluminum alloy structures. At present, there is little research on welded joints of aluminum alloy, which seriously hinders the development and application of aluminum alloy structures. Therefore, the paper studies the welded joints of aluminum alloy structures with actual site welding conditions. Four box-type aluminum alloy welded specimens are designed and tested with the static load. The force transmission components of the joints include vertical ribs and cover plates. The results show that the rib and cover plate can effectively increase the bearing capacity and ductility of the joint, and the increase of the vertical rib elongation also has a significant improvement on the capacity of the welded joint.
