Defect features in Friction Stir Welded joints

Year: 2019

Type: article

Abstract: Friction stir welding (FSW) is nowadays used to join similar as well as dissimilar metals and their alloys. Defect formed during the FSW process can adversely affect weld quality. The present study gives an overview of the various defects formed in friction stir welded lap and butt joints. The welds were analyzed to understand the effect of process parameters, namely tool rotational speed and tool traverse speed, on defect formation. The formation and prevention of the main weld defects in friction stir welded joints, such as tunnel, channel, wormhole, kissing bond, hooking, cold lap, cracks and micro cracks, void, porosity, and flash is discussed. Further, the detrimental effects of the defects on weld performance are discussed.
