Weld Overlays

Weld overlay (WOL) is one of the useful repair methods for cracked piping that has been successfully applied for piping in many nuclear power plants. In addition, ASME Boiler and Pressure Vessel Code Section XI provides a WOL method in Non-mandatory Appendix Q and a number of Code Cases. Currently, an analytical evaluation method for predicting failure stresses for WOL piping is under discussion in a working group of ASME Code Section XI. This paper proposes an approach for predicting the plastic collapse moment for WOL piping using a net-section collapse stress approach. In addition, the predicted collapse moments are compared with experimental data.
