Dissimilar joint with good quality and mechanical properties is one of the major problems the industries. One of the most commonly used methods to solve this problem is friction stir welding process. In this paper two different tool pin with simple cylindrical and screwed profile were used to finding optimization of friction stir welding parameters to reach best mixing flow, composite structure...

It is important to join materials for systems that require high-performance and minimize the defects may occur during this joining. Welding most common way joining but lightweight similar/ dissimilar materials, Friction Stir preferable its properties. Lightweight durable such as aluminum alloys are widely used in sectors defense industry, aerospace automotive high-speed train manufacturing. Som...
