Thin-walled aluminum alloy tubes utilized for industrial applications like aviation and car manufacturing can be produced by various processes which are mainly divided into seamless and welded tubes. The utilization of welded tubes is desired to meet the increasing need for production efficiency and flexibility in design particularly when the shape cross section is asymmetrical. In this study, the possibility of attaining the defect-free and manufacturing of friction stir welded tube of AA 6061-T6 having a wall thickness of 2.5 mm was carried out and process parameters were optimized to get a visually defect-free welded tube. In the next step, the characterization of welded tubes using rotary draw bending of the welded tubes was done. With the increase in the welding speed, the average ovality in bent tubes was decreased and with the increase in the bending speed, the ovality was decreased in rotary draw bending of friction stir welded aluminum tubes. تفاصيل المقالة
