N2 - This work presents, for the first time, and estimation of fracture toughness KIC correlations from Charpy V-notch (CVN) impact test data extracted from T-welded connections repaired with rectangular grinding and filled by wet welding. To obtain KIC values, equations based on the yield stress (σYS) of the wet welding beads were used. The estimated KIC data decreased with increasing water depth. These two characteristics (porosity and microstructures for low carbon steels) did not improve the mechanical properties, such as Charpy impact and KIC values.
