Abstract

In this study was analyzed the effect of tool material, tool geometry and process parameters on mechanical properties and microstructure of friction stir dissimilar welded AA7075 and pure copper joints. Different welded samples were produced by varying tool material H13 and HSS, tool geometry like cone pin length 4.8 and 5 mm, the rotational speeds 750 and 900 RPM, and in all experiments, the feed and tilting angle are constant at 16 mm/min and 2°. These parameters were used for better understanding the effect of dissimilar AA7075 and pure copper welded joints on tensile strength, microstructure and hardness. Results showed that the good strengthen AA7075 and pure copper friction stir welded joints could be obtained when a tool is H13 material and cone-shaped tool. H13 tool gives quality AA7075 and pure copper friction stir welded joints compare to HSS tool at speed of 750 Rpm, feed of 16 mm/min and tilting angle 2°.
