Abstract

In this investigation, separate AA6061-Al and AZ80A-Mg alloy plates were effectively joined through stir welding with friction. We looked closely at the weld joints’ characteristics, especially their mechanical aspects. In the experiment, here were multiple tool rotating rates (rpm) of 800, 1000, 1200, 1400, and 1600 used. A cylindrical pin-equipped tool featuring a tapered profile was utilized, inserted into the AA6061 alloy plate is offset by 0.5 mm, while maintaining a 30 mm/min constant traverse speed. The experimental findings indicated that optimal levels of frictional heat were achieved when 1200 rpm was the rotational speed of the tool. As a result, this specific joint exhibited a notable tensile strength of 225 MPa, representing approximately 77.76% of AZ80A’s tensile strength and 72.25% of AA6061 alloy. These results underscore the significance of rotating speed of the tool in influencing the mechanical performance of stir-welded friction joints between distinct aluminum and magnesium alloys

Keywords: friction stir-weld, tensile test, tool speed, traverse rate, aluminum and magnesium alloys
