INVESTIGATION ON FRICTION STIR WELDING OF DISSIMILAR ALUMINIUM ALLOYS AA 7075 AND AA 1200 BUTT JOINTS
ABSTRACT Dissimilar aluminium alloys of AA1200 and AA7075 have significant applications in automobile sector, aerospace, defence and shipping industries. These alloys faces problems like hydrogen solubility, formation of aluminium oxides, solidification shrinkage etc when welded with fusion welding process. Friction stir welding is the process which is able to successfully weld these dissimilar alloys of aluminium. Process parameters like rotational speed, welding speed, tool design, vertical force plays important role ...
