Mechanical and Microstructural Properties of Dissimilar Friction Spot Welded Aluminum Alloy
Dissimilar friction spot lap joining of Al5052 and Al6022 sheet has been investigated using a combination of joining parameters, thickness and upper plate material. The joining parameters such as tool rotating speed, plunging depth and joining time have been considered. The maximum tensile shear strength has been observed at tool rotating speed of 1000rpm, dwell time of 2.5sec, plunging depth of 1.8 mm and Al 6022 as upper plate. The maximum tensile shear fractured load of the joint was about 80% of that of the similar Al 5052 alloys joint.
