A novel multi-container extrusion has recently been proposed to extrude multiple billets simultaneously for manufacturing thin-walled wide engineering components with greatly reduced force. The metal flow behaviour and solid-state welding in the process are crucial factors that influence final product quality industrial application. In this study, AA6063 hollow profiles were extruded by three-c...

This work describes the effect of newly introduced faying surfaces on microstructure and mechanical properties dissimilar weld joints AA6063 AISI304L alloys that are fabricated through rotary friction welding process (RFW). The experiments were done as six different experimental methods (‘A’ to ‘F’) at 1300 rpm rotation, 18 MPa pressure (FP), 24 upset (UP) 5 s time (FT) with hemispherical bowl ...

A recently developed solid-state joining technique called “friction stir spot welding” (FSSW) is used to combine metal alloys with low weldability. Significant experimental work for this study concentrated on the FSSW of AA6063 and AA5083. The involved fixture setup welding pattern parameters sizes material, all which were done a milling machine. cylindrical shoulder concave (10°) square pin pr...
