Abstract
Friction stirs processing (FSP) is a method of changing the properties of metal through intense, localized deformation. Where Friction Stir Welding (FSW) is Mechanical joining properties are dramatically pushed into deterioration when a tunnel defect is formed. FST is effect found due to regulated heat input and regulated material flow. Sometimes defects in the weld are generated applying certain variations in welding parameters. In this study, the tunnel formation in AA 3102 was experimentally studied by taking various parameter incorporating speed and feed. The effect of tunnel formation was evaluated by Radiography test. Here we are creating the tunnel through the length and which dimension can be control by tool geometry, spindle speed, and feed rate. This experimental investigation covers methodology to enhance the word “defect” to “tunnelling effect” which is created by changing some parameter during processing and welding.
