Friction welding is one of the versatile and well established welding processes solid state joining of the materials through the controlled rubbing of the interfaces. Friction welding is used in many fields because the procedure is easily automated and it is possible to weld dissimilar materials.Friction welding (FW) is a solid state joining method which produces coalescence of materials under compressive force when the workpieces rotate or move relative to each other producing heat and plastically displacing the material from the faying interface .There are many different methods of friction...
