Modeling and Simulation Based Analysis of the Matter Flow During Friction Stir Welding Process

Friction Stir Welding (FSW) is a recent assembly process which has been developed at the British Institute (TWI) beginning of 90's. This welding gone rapid development and an increasing success. Many remarkable industrial applications achieved mainly in spatial, aeronautical, automobile, railways, marine naval industries.... The translation rotation tool during FSW generate flow plastic deformation material had often differently interpreted contradictory manner. In this paper, analytical model proposed to describe matter vicinity pin process. Analytical solutions are elaborated on basis conventional fluid mechanics theory used solve associated equation mentioned problem based Laurent's series (called also development). knowledge around can lead better understanding metallurgical phenomena have significant effect mechanical properties welded joint allows description speed fields worth full for thermal modelisation since great part power generated by auto-heating energy. results obtained speeds good accordance with experimental found literature. study highlights gives phenomenon
