摘要：Friction stir welding is a unique and promising technique to produce joints with desirable
mechanical strength and properties. Tailor welded blanks are processed by joining two
plates of dissimilar thickness with relatively less mass. As tailor welded blanks offer
higher strength at a minimal weight, the material consumption decreases making it more
economically viable. In this study, the influence of the critical friction stir welding
process parameters namely tool traverse speed, tool rotation speed and thickness
mismatch ratio on the microhardness, corrosion rate, tensile strength (before and after
corrosion) of AA5052 tailor welded blanks are investigated. The friction stir welding
trials were conducted based on Box Behnken design at three levels of process parameters.
Hybrid-Radial Basis Function based models were developed to explore the effect of
process parameters on the properties. The optimum process parameters to obtain high
tensile strength in AA5052 tailor welded blanks was found to be tool traverse speed of
60mm/min, the tool rotation speed of 850rpm and thickness mismatch ratio of 0.9.
