چکیده مقاله:
Using friction heat, welded joints of the Friction stir welding (FSW) process are made that are utilized to forge metal components together. Since there is no parent metal melting, several advantages are obtained by the FSW process over fusion welding. The alloys AA۶XXX and AA۷XXX Al are two sets of the most extensively utilized structural materials in rail transportation, automotive, and aerospace industries. The objective of present study was to investigate the effects of novel cross-sections in joint lines and further analyze the improvement in mechanical features. Due to the importance of the weld zone properties, many researchers seek to improve the mechanical behavior of the weld zone. For this, friction stir welded joint under four different new design in cross section named E۱, E۲, E۳, E۴ and one conventional cross section, E۵ were conducted. Better outcomes are obtained by joints made utilizing this method based on joint quality and strength. The very good tensile features are displayed by the fabricated joints with Ultimate Tensile Strength (UTS)> ۲۵۴ MPa and elongation > ۷%. The highest UTS value which is occurred in E۳ condition (Downward step) is ۲۴.۷% higher than required for FSW of AA۶۰۶۱ alloy at T۶ condition in the American Welding Society (AWS) standard (۱۸۶ MPa).
