Abstract
Friction Stir Welding FSW is a solid state Welding Process that allows or dissimilar Materials to be welded. However, the process requires a careful selection of process parameters to produce consistently reproducible defect free joints. The paper presents contributions to a possible classification of FSW induced flaws, underscoring their relation with the process parameters. Although the flaws generated by FSW have already been classified as flow, and geometry related, respectively, a standard classification does not exist by now. The geometric related flaws are associated with lack of penetration and occur due to insufficient pin penetration depth and/or improper seam tracking. The flow related flaws include flash formation, surface galling, lack of fill, wormholes, and lack of consolidation.
