Modelling weld residual stresses

The High Temperature Performance (HTP) Research Group at the University of Nottingham has developed new procedures for simulating the weld process using Finite Element (FE) techniques.

This approach allows the simulation of thermal-mechanical interaction of each weld bead, resulting in the prediction of the overall residual stresses in the weld. The WELDON project has provided a valuable set of experimental measurements that have been used to verify the FE simulations.

The weld simulation techniques will continue to be improved and have already been applied to other types of high temperature pipe welds used in power generation plant. The work has resulted in a number of publications in international journals and conferences.
