An Experimental Investigation and Process Parameters Optimization of Friction Stir Welded Dissimilar Alloys

In this present study, FSW is joining the two dissimilar aluminum alloy sheets (AA6063 and AA5052) to examine on the hardness. The experimental method Taguchi L9 orthogonal is implemented to create the amount of welding tests. Using the wire cut EDM, the conventional ASME hardness skeleton is obtained. The sheets are efficiently joined together and the sample sheets are tested at room temperature using a Rockwell hardness tester to fine-tune the welded specimen's hardness. Analysis of ANOVA testing is conducted in order to obtain the most suitable (optimum) range of selected parameters and their results on hardness welded joints. The outcome indicates that the welding speed is 620rpm, the feed is 30 mm / min, and the tilt angle 1 are the important parameters of the method to join these different joints.
