AA 5083 Aluminum alloys begin to be replaced steels in automobiles, ships, and high-speed-trains by providing reduced energy consumption and low carbon emissions thanks to their low densities, good weldabilities, and high corrosion resistance. During the production of high-speed trains, which are of special importance for our country, the proper selection of joining method for AA5083 increases the production speed. In this study, AA5083 alloys with 8 mm thickness were butt-welded under different parameters by using MIG and TIG weldings. It was aimed to determine the changes in microstructure and mechanical properties of welded samples, and also to specify the proper welding method. As a result, it was found that samples joined by MIG welding have higher strength and ductility, along with a lower amount of microstructural defects compared to their counterparts joined by TIG welding.
