Abstract: Surface coatings made with different methods change the surface properties of metallic and non-metallic materials and improve properties such as wear resistance.As a result of a hard surface coating, the surface is protected against wear, but problems may arise in arc and highenergy welded joints.Besides how the general properties of the coating layer change after the welding process, the mechanical properties of the welded joint are also important.In this study, tungsten carbide (WC) coating was carried out on AISI 1010 steel by ESD method at constant current using different frequencies and voltages and later two identical specimens were joined by spot welding at constant current and pressure.In order to reveal the welding zone, the samples were sliced into two, and then moulded and classical metallographic processes were applied.After metallographic processes, images were taken with an optical microscope and Electron microscopy to examine the microstructures formed in the weld zone.The results show that WC coated steel sheets cause localized alloying in the weld zone and therefore drastic changes in microstructures.
