FSW is a pollution-free welding process used for joining similar or dissimilar alloys. AA6082 T6 and AA5052 aluminum combinations were chosen for FSW due to their unique properties and applications. Mostly these alloys are used in many applications such as automobile, aerospace, shipbuilding, etc. In this research, a plan of trial approach was utilized, with 15 exploratory runs differing in the FSW boundaries as per foreordained levels. The outcomes showed that the FSW boundaries fundamentally affected the elasticity and hardness of the welded tests. A factual investigation involving relapse conditions uncovered the ideal boundary settings for accomplishing wanted weld quality.

This paper provides an overview of the recent research on “Friction Stir Welding (FSW)”. The objective of the work is to summarize the prominent research work in this field with due emphasis on the methodology involved, workpiece materials, tool design and material, workpiece sizes as well as the typical process parameters involved. A brief account of the numerical analysis of the FSW process has also been presented. The applications and future prospects of the concept have also been briefly discussed.

One solution to overcome the challenges associated with this scenario is enhancing manufacturing process capability. At the same time, developing products that have greater market demand. Manufacturing alloy steel components are one such area that has wide commercial viability. Alloy steels possess superior mechanical properties and exhibit very good serviceability and resistance to adverse environment. Machining of alloy steels through conventional processes involving flood cooling has its own demerits. Cost and environmental issues are the major concerns in this context. Therefore, developing an alternative lubrication technique such as near dry machining has been an area of rigorous research over the past few decades. It offers significant advantages in terms of operational economy and environment friendliness, without affecting the process effectiveness. In this work, near dry machining, also referred as minimum quantity lubrication (MQL) technique, has been usedfor lubrication in turning operation of EN-8 alloy steel. System variables such as flow rate, pressure and the nozzle stand-off distance have been chosen to analyze the effect on cutting force. The experiments are based on a central composite design (CCD). A mathematical model to define the relationship of these variables with the cutting force has been developed. It would be helpful in predicting and enhancing tool life.
