of the structure. There are also situations where no sealing is applied, leading to
water traps. Some defects in welded connections can also be detected by visual
inspection, namely planar imperfection, slag inclusions, pores, undercut and/or profile imperfections [3] (Figures 8.6 and 8.7). The major effect of weld imperfections on
the service performance of steel structures is to increase the risk of failure by fatigue
or by brittle fracture.
