In order to increase the joint strength. RFSSW is used to weld 2524-T3 aluminum alloys of aircraft skin. The joint Connection Mechanism is studied through the analysis of its appearance and microstructure by SM and metallographic microscope. The mechanical properties of the joint is investigated by tension-shear test and cross-tension test. https://countryscenesaddleryandpetsuppliers.shop/product-category/leg-wraps/
