Abstract

In this paper, the effect of different workpiece geometries on the properties of welded Al-7075-T6 partsin rotational FRICTION WELDING process has been investigated by using experimental and finite elementapproaches. Welding process is continuous drive FRICTION WELDING. In this research, the samples diameterwas selected equal to 25 mm and the samples length was selected equal to 75 mm. The processvariables such as friction time (t1), forging time (t2), friction pressure (P1) and forging pressure (P2)were assumed to be constant, whereas ROTATIONAL SPEEDs were variable and selected equal to 2000 rpmand 2500 rpm. Three cylindrical parts with different cross sectional geometries were adopted as threesamples. Finally, to verify the accuracy of numerical analysis, the experimental and thermo-mechanicalsimulation results were compared and good agreement was found between them. Since an experimentaltest is a time consuming and a costly process, it was decided to obtain more results by using analternative method such as finite element simulation technique. Results of this study showed thatchanging in front geometric of workpiece is an effective factor for tensile strength, length of workpieceand generated flash in welded area and by changing this factor, properties of welded area can beimproved.
