- Friction stir welding (FSW) is a solid-state joining process that uses a non-consumable tool to join two facing work pieces without melting the work piece material.[1] Heat is generated by friction between the rotating tool and the work piece material, which leads to a softened region near the FSW tool. While the tool is traversed along the joint line, it mechanically intermixes the two pieces of metal, and forges the hot and softened metal by the mechanical pressure, which is applied by the tool, much like joining clay, or dough.[1] It is primarily used on wrought or extruded aluminium and particularly for structures which need very high weld strength. FSW is an eco-friendly process because there is no fumes production and no filler material. To get high quality of weld, then high heat should be generated. In this paper, AA6063 and AA7075 alloy material is welded by En8 tool with different parameters and quality of weld is examined by using a non-destructive testing method called Ultrasonic and Radiography inspections. FSW is also found in modern shipbuilding, trains, and aerospace applications.
