Joining of plastics finds applications in medical, aerospace, electronic and automotive areas. Present study emphasizes on joining of thermoplastics and thermoplastic composites by two recent techniques namely Friction Stir Welding (FSW) and resistant welding. The processed joints were analyzed by mechanically and metallurgically. This study also describes a new method of the selection of process parameters for obtaining optimal weld/joint strength by non conventional optimization techniques.
