Abstract
This paper reviews; the geometry of tool and its parameter’s which effect on properties of similar materials weld joint have been studied. Joining similar alloys AA5082 is used in automotive components, transmission towers, structural or architectural, frames and scaffoldings because of its characteristics. For the joining of low melting point materials it is difficult in fusion welding. To reduce that problem, researchers used a solid-state technique for welding such as Friction stir welding. The tool geometry and its parameters play a crucial role in the welding for better mechanical properties and good weld joint. The plastic deformation of the material in friction stir welding process depends on the tool size; heat generation depends on the shoulder size; the grain size and morphology depend on the heat generated at the weld joint. The main aim of this review is to discuss the tool geometry and their parameters used mostly and mechanical properties to have a good weld joint.
