Abstract: Friction stir welding (FSW) is a modern, innovative and efficient welding method for welding materials that are difficult to weld by traditional methods of fusion welding. Welding parameter plays an important part in determining weld performance. The correct choice of welding parameters will result in sound welds, which will enhance the material's mechanical properties. Radiography and ultrasonic analysis are very effective ways of detecting and measuring faults or harmful defects without altering materials functionality or serviceability. Aluminum alloy is a material of light weight and has many industrial applications. However, traditional fusion welding methods do not allow them to be easily welded because the consistency of the welded joint is compromised due to porosity, hot cracking and distortion. In this paper FSW technique welds AluminumAA-5083 with variation of the tool's rotational and transverse speed. Ultrasonic radiography and immersion testing was conducted to identify various defects on the welded materials. It is found that as transverse velocity increases, the heat input generation decreases which cause the cavity or groove like defects.
