Abstract
In this paper,the welding parameters in friction stir welding of 6005A-T6 Al alloy extrusions used in side wall of metro train were optimized.Based on the welding parameter window with rotational speed of 1000-2100 r/min for and welding speed of 500～2 200 mm/min obtained in preliminary experiments,a spindle speed of 1 500 r/min and welding speed of 1 100 mm/min were determined as the optimal parameters via comparing the appearing quality of welding seam.Metallographic analysis and tensile and bending tests were performed for joints welded with different axial forces.With a spindle speed of 1 500 r/min,welding speed of 1 100 mm/min and axial force of 13.5 kN,defect free joints could be obtained,while the tensile strength reached 80％ of base metal and no fracture occurred in 180° bending tests.关键词
