Parametric Optimization of Friction Welding Process

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 welding processes; some important methods have Rotational, Linear, Angular or Orbital types of relative movement between the joining parts. In this research optimization is done by using factorial design technique which is effective for various welding technologies in investigating the effect of process parameters on weld quality in terms of mechanical properties by using rotary friction welding.In this experiment, 6061-T6 aluminium alloy is used as a base material, because it is widely used in different fields like the automotive, railroad, chemical and oil industries.
