Microstructural and Mechanical Properties of Welded Joints in Tig, Mig and Friction Stir Welding -Review

Abstract

In the manufacturing industry today, welding is a very important process needed for fabrications and revamping metal products. Researchers continually look for the best types of welding to be used for various joints. A lot of experiments had been carried out varying welding parameters and studying its effects. This paper basically reviews the residual stress effects on the welded joints of Steel, Magnesium and Aluminium alloy with their experimental analysis. The performances comparison of TIG, MIG and Friction Stir welding were also considered through check of their microstructure, mechanical property, young modulus, stress and yield stress of their welded joints. This has been able to show different behavious resulted from various welding mode of a welded joint.
