Abstract
Friction Stir Welding (FSW) is a solid state welding process used for welding similar and dissimilar materials. This welding technique allows welding of Aluminum alloys which present difficulties in fusion joining and allows different material couples to be welded continuously. In this study, 1050 aluminum alloy and commercially pure copper to increase heat input were produced at high rotation rate (2440 rev/min) with four different pin position (0-1-1.5-2 mm) and three different weld speeds (20-30-50 mm/min) by friction stir welding. The influence of welding parameters on microstructure and mechanical properties of the joints was investigated. Tensile and bending tests and microhardness measurements were used to determine of mechanical properties. Nugget zone microstructures were investigated by optical microscope and scanning electron microscope (SEM) and were analyzed in energy-dispersive X-ray spectroscopy (EDX). Depending on the XRD analysis results intermetallic phase was observed to form in the interfacial region. In the tensile test results, 83.55% weld performance was obtained in the friction stir welding merge of Al-Cu.
