Abstract
The following is a review paper on corrosion analysis of friction stir welded aluminium alloys. It is proven from several experiments and researches that friction stir welding is preferable to conventional arc welding processes when one wants to increase the corrosion resistance. But the effect of cryogenic treatment on the welds is yet to be studied. This review paper is a combination of the works done on corrosion analysis of aluminium alloys, preferably AA5083.
