OPTIMIZATION OF PROCESS PARAMETERS OF FRICTION STIR WELDING/PROCESSING FOR DISSIMILAR ALLOY-A REVIEW
Keywords:
Friction stir welding, Microstructure, Strength, Aluminium alloyAbstract
Friction stir welding (FSW) is a process of joining of two similar or dissimilar material which uses nonconsumable rotating tool. Friction Stir Welding (FSW) was developed for microstructural modification of material and the effect of the welding parameters such as tool rotation speed, welding speed, tool pin diameter, shoulder diameter and tool pin profile have a significant effect on tensile strength, micro hardness, yield strength and strain rate of friction stir welding.
This review provides an overview of the effects of the Friction stir welding on microstructure refinement, tensile strength of welded joint, and tribological properties. This review conclude with recommendations for future research work.
