Finite Element Modeling in Friction Stir Welding of Two Dissimilar Pipes

The Finite Element Modeling has been achieved for two dissimilar pipes welded by friction stir welding for given operating conditions and cases. Moreover, this analysis has been carried out to find the effect of hydrostatic pressure test on the welding area of the pipe by ANSYS Workbench software. In this study dissimilar materials of different pipes were used for FSW, which they were joined as 6063 aluminum alloy pipe with 6082 aluminum alloy pipe and C36000 high-leaded brass pipe with C12200 copper alloy pipe. In this study six parameters were used and with those parameters, eight (8) cases were welded and examined with hydrostatic tests and tensile test. The process was accomplished by varying one of the parameters (rotation speed) and keeping the others as constants.
