Friction Stir Welding (FSW) is a relatively new solid-state joining process. This joining technique is energy efficient, environment friendly, and versatile. In FSW parameters play an important role like tool design, tool rotational speed, and axial force. To get effective welding joint need to concentrate on process parameters on FSW. Weld quality is predominantly affected by welding input parameters. The welding input parameters in FSW are tool Profile, tool rotational speed, and axial force play a major role in deciding the joint strength. The average FE tool value of weld strength for plan...
Friction Stir Welding (FSW) is a relatively new solid-state joining process. This joining technique is energy efficient, environment friendly, and versatile. In FSW parameters play an important role like tool design, tool rotational speed, and axial force. To get effective welding joint need to concentrate on process parameters on FSW. Weld quality is predominantly affected by welding input parameters. The welding input parameters in FSW are tool Profile, tool rotational speed, and axial force play a major role in deciding the joint strength. The average FE tool value of weld strength for plane surface tool is 172.27 MPa. The average practical value of weld strength for plane surface tool is 218.91 MPa. The average value of weld strength for conical surface tool in FE tool 177.93 MPa. The maximum weld strength at 822.18oC both conical and plane surface tools are having 207.75 and 205.57 MPa. The average percentage of error is 21.29 for plane surface tool between the practical values and FE tool values. These values are observed that weld strength increase by using conical tool. In present work an attempt has been made to join the pure copper by using FE tool.
