A Comparative Study ON Friction Stir Welding Ofdis-SIMILAR METALS By Using Lathe Machine used to fabricate the joints are shown in Fig. 2. An indigenously designed and developed lathe machine (3HP,1400RPM) has been used to fabricate the joints as shown in Fig.3. In each pin profile, two tools have been fabricated with two shapes of pin profile (i.e., circular pin and taper pin) and same shoulder diameters (D) have been fabricated, each tool is used to fabricate one butt joints and hence 6 joints have been fabricated in this investigation. The welding parameters and tool dimensions are presented in Table 2. The welded joint and samples are prepared as per the dimensions of tool post in lathe machine as shown figure
