Impact of Different Process Parameters on the Strength of Welded Joint in Friction Stir Welding
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 6
Abstract
Friction stir welding process is used to combine high strength aluminum alloys, thermoplastic material and other metals also. In Friction stir welding high temperature results in excessive heat generation which ultimately results in various defects that leads to failure of the welded joint. Welded joints are defined on the basis of their strength which includes both types of strengths yield as well as tensile strength that termed as mechanical strength that shows how efficiently it will work, when heavy load is applied without any kind of rupture or failure. This paper presents the variation in the behavior of the welded joint while changing the different process parameters i.e. transverse or welding speed, rotation of spindle, axial force and pin profile of welding shoulder. Different experimental data is used to obtain the relationships between all process parameters and their effects on the mechanical strength of a welded joint. In this paper large number of welding defects as well as different type of failures is analyzed using the final temperature of the welding process which is having great effect on the granular structure of the welded joint.
