Welds in safety critical applications are subject to structural integrity assessments where residual stress plays a key part. Dissimilar welds are often used in service without stress relief which means knowledge of residual stress is even more important. Because residual stress predictions are unreliable, experimental measurements such as neutron diffraction and deep hole drilling (DHD) are essential.We will measure the residual stress profile in a P92 steel pipe welded using a superalloy. This task is a part of the SUPERGEN consortium that aims to improve the efficiency of power plants. Neutron diffraction has been used for residual stress measurements in simple welds, but dissimilar welds present a challenge due to their complex microstructure.Residual stress will be measured at locations in the welds. The results will be compared with DHD measurements.
