Experimental analysis on friction stir welding process parameters on temperature distribution

In most cases fusion welding of aluminium and its alloys is difficult because of their low melting point despite many useful properties like high thermal conductivity, less corrosive nature and light-weight. Although successful, but the implementation of FSW is difficult due to lack of literature, like parameters such as temperature distribution, torque etc., are not fully developed. In this project, the temperature distribution in Al alloy welding sample during Friction stir welding at different parameters has been analysed. The experiments were carried out in the universal milling machine where mild steel is used as a tool, which was prepared in the centre lathe machine available at Assam Down Town University workshop. The experiments were performed by varying the weld parameters such as feed rate, spindle speed and probe diameter. The temperature of welding specimen is measured at different zones of welding sample with the help of a laser temperature gun.
