Studying the mechanical and Numerical properties of Friction stir welding (FSW) for 6005 aluminum alloys

Abstract

Friction Stir welding (FSW) is a welding method that occurs without fusion and smoothed the granules, used to improve the fine structural properties of metals. In this paper, the enhancement of mechanical properties for FSW samples at rotation speeds (1000, 1100 and 1200 rpm) with welding speed (45 mm/min) for 6005 AA is studied by using the method of FSW at the same variable rotating speed and feeding speed. In order to convert a heterogeneous nanoscale structure to a more precise and homogeneous monolithic structure. The best welding results obtained at parameter 45 mm/min are welding speed and rotational speed of 1100 rpm at FSW where efficiency reaches 96% for FSW for maximum tensile strength of mother metals. The FSW was developed as a finite element simulation of (FSW) of 6005 AA. Numerical simulations of thermal conductivity, heat and specific density were developed to find out the relationship between these factors and maximum temperature.
