Özet

The use of magnesium, which is the latest metal of our age, is increasing in parallel with the advances in industry and technology. Due to its lightness, durability and long life, its usage is increasing in the automotive and space-craft industries. As a result of the advances in magnesium use, there are innovations in welding methods as well.  The desired mechanical properties can’t be obtained after welding. While there are some difficulties in fusion welding of magnesium material and its alloys, some of them can’t be joined by fusion welding at all.  Weldability of a material is the property that plays an important role in enabling its wider use and determines the method of producing products out of this material. Magnesium plates were joined successfully by friction stir welding method. Welded joints are exposed to various mechanic stresses and especially to dynamic loads. Cracks are observed to occur due to dynamic loads. Plates were joined in butt position and the mechanical properties of the occurring joint are examined
