چکیده
In the friction stir welding (FSW) process, a special rotating tool is used for welding different parts without utilizing any electrode as filler material. By rotating the cylindrical tool and sinking it into the line of connection between two parts, friction and disturbance are created, and at the same time, heat and pressure also rise to prepare the conditions for the welding. During the last two decades, a large number of research has been carried out to investigate the mechanical properties and microstructure of joints made from several similar and dissimilar alloys. Crack growth resistance of such joints under tensile, shear and mixed loading is an important design parameter to evaluate the lifetime of welded parts in friction stir welding, while there is limited research on combined mode I/II in FSW welding. To fill this research gap, in this research tensile and fracture strength in dissimilar FSW welding of AA۵۰۸۳/AA۵۰۵۲ aluminum alloys are investigated experimentally. For this purpose, two pin diameters, three pin rotation speeds and welding speeds have been selected as welding variable parameters. After carrying out the welding, the tensile and cracked mixed mode fracture tests were performed to determine the effect of considered parameters on the tensile and fracture strength of the joint. The results showed that the biggest tensile and fracture strength happens in different tool rotation and welding speeds for different loading angles (fracture modes).کلیدواژه ها
