Özet

Nowadays, with the widespread use of additive manufacturing applications, it has become important to join the parts obtained from this production method with other materials. In this study, it was aimed to investigate whether the AlSi10Mg alloy produced by additive manufacturing can be joined to the AA5083 alloy, which is widely used in industrial applications, by friction stir welding (FSW) method. In this status, sheets produced in dimensions of 200x50x4 mm3 were used. FSW was performed using a tool with triangular pyramid geometry with a travesting at 85 mm x min-1, rotation speed of 800 rpm, and pressure force of 7 kN. The tilt angle of FSW tool was kept constant at 2°. FSW was performed using A tungsten carbide (WC) tool consisted of a shoulder with the diameter of 18 mm and the 30° cone angle. After the FSW, the specimens were taken from the joint areas to investigate the structural and mechanical properties. It is observed that a very fine-grained structure emerges in the mixing region.  The tension test specimens were taken from the FSW zone parallel to the welding direction by wire-electron discharge machine (EDM). Tensile tests were performed using the shape of a dog-bone specimen which in accordance with the ASTM E8. The tests were carried out using a tensile tester at 1x10-3 s-1 strain rate. Evaluations were performed by comparing the findings with the base materials.
