Microstructural Evaluation And Eff ect of Heat Generation in FSW of AA1100

In this work the joining AA1100 aluminium alloy using friction stir welding (FSW) is demonstrated. The process parameters used in this research work are welding speed, rotational speed and axial load. The responses considered in this work include tensile strength and hardness of the welded specimen. The microstructural analysis are investigated to identify the HAZ and TMAZ in the FSW of AA1100 Aluminium sheet metals. The thermal analysis is also carried out using ANSYS software and it is observed that the maximum temperature is maximum at the centre and the maximum deformations will take place at centre of the welded plate when subjected to the external loads.
