In this research, AA 2024-O aluminium material, which is specifically used in aircraft and aerospace industries, was used. Aluminium plates were welded with different methods: tungsten inert gas welding (TIG) is a fusion based process; and friction stir welding (FSW), a solid state process, has held great importance in welding of aluminium and alloys recently. Extracted samples from welded plates were tested for fatigue strength, tensile strength and hardness. The results of experimental studies show that friction stir welded plates provide better on overall basis.
