Abstract

The Friction Stir Welds mainly depends on the three factors Tool pin which is the joining material will properly mixed during joining. FSW machine primarily used to control the critical parameters used in the specific range. The tooling fixture needs to be perfectly positioned and locate the work piece accurately as well as to dissipate the heat that imparted during welding. Most of the significant parameters are affected and controlled by input parameters like tool tilt angel, axial load, spindle speed and transverse speed of the work table. The physics behind the FSW process includes various stages such as the tool pin rotates and plunges into the parent material with larger amount heat generation and reaches the plasticized formation. Then the tool approaches the predefined tool path and makes the joining by stirring action by the shoulder of the tool. In recent days this process can also performed joints underwater submerging with dissimilar alloys. Joints are made by using ultrasonic vibrations for pipes under quality monitoring systems were also employed. The real challenges are still depends upon the reliability and durability of the weldments.
