Abstract

The friction stir welding of AA1100 aluminium alloy is experimentally investigated and analysed in this work. The weld quality of FSW is analysed and optimized for the welding process parameters such as weld speed, tool rotational speed, tool pin geometry and axial load in this work. The tensile strength of the welded specimen is considered as the response and response surface methodology is used here to establish a relationship between the factors and the response. In this work a mathematical model using the multiple regression equations for friction stir welded aluminium plates are established and analysed using ANOVA. It is observed that the tool pin shape with square geometry contributes to higher tensile strength when compared to the other tool pin profiles. Also it is seen that as the feed and axial load increases there is an increase in tensile strength of the welded specimen
