Effects of Friction Stir Welding tool rotational speed on Microstructure and Hardness of the Industrial Aluminum

Friction stir Welding is the type of welding used as a solid state joining process for materials because it deflects the common problems obtained in conventional welding processes. The reality that joining of alloys could be usually faced problems in many sectors that includes automotive, aerospace, ship building industries, electronics etc. where fusion welding is not possible due to large difference in physical and chemical properties of the components to be joined. Industrial Aluminum 2xxx Series is widely used in aerospace industry. In the Friction Stir Welding, the rotational speed of tool effects on Industrial Aluminum Microstructure and Hardness of welded zone.
