In order to achieve a high-quality joining of aluminum (Al) and copper (Cu) dissimilar metals, new friction stir double-riveting welding (FSDRW) with Cu rod as the rivet was proposed, rotating tool large concave angle shoulder specially designed. The results showed that under thermal–mechanical effect tool, deformed be double riveting heads structure anchor at upper surface Al plate an above la...

Abstract: AISI 316L steel and Inconel 718 are metals of wide application in industries. The study dissimilar welding between these two materials is technologically important to improve their joint performance. We focused this on the evaluation weldability materials. Three samples welded using a multipass GTAW (Gas Tungsten Arc Welding) process with different parameters were analyzed. microstruc...

Studies on dissimilar metal welding and mechanical fastening using metallic glasses in Utsunomiya University have been introduced. Metallic glass ribbons placed between the two plates become supercooled liquid with low viscosity by resistance promote supercooling at nuggets. As a consequence, residual stress boundary formation of brittle intermetallic compounds are suppressed, resulting excelle...

In this study, arc and friction stir hybrid welding (AFSHW) was proposed to weld aluminum-steel dissimilar metals in attempt realize high quality joining. Firstly, an interlayer produced on galvanized steel by using bypass current-metal inert gas (BC-MIG), then aluminium plate jointed via Friction lap (FSLW). The effects of tool pin length FSLW times the microstructure mechanical properties joi...
