【 摘 要 】

Friction Stir Welding is a new innovating process of joining of two work pieces. It is an relatively a new joining process and highly useful in welding method, which can produce high strength weld without using any toxic materials like electrodes. In this method, weld is obtained by frictional produced between shoulder and work piece [1, 2]. Main parameters which are to be considered for FSW are spindle speed and feed rate. By providing suitable parameter during welding defects will not be occurring. Also, 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, Al-6061 material is welded by H-13 tool with different parameters and quality of weld is examined by using a non destructive testing method called Radiography.
