Abstract

The most important advancement in metal joining during the last few decades is the Friction Stir Welding (FSW) process. When welding magnesium or light weight alloys, FSW offers several benefits. Due to its advantages in lightweight construction, friction stir welding of magnesium alloys are widely used in the aerospace, marine, transport sector, particularly in automobiles and trucks, where they may significantly increase fuel economy and reduce emissions. Research and development in the area of FSW and related technologies have recently been advancing quickly on a global scale. The fundamentals of friction stir welding and a number of characteristics of friction stir welded magnesium alloys have been discussed in this article. Furthermore, this review reports the summary of the present status of friction stir welding of magnesium alloys with automotive applications. In addition to that, the properties, structure, flammability and wear behavior of magnesium alloys have been described.
