Our proven capability
As part of a government funded program to develop the capabilities needed for future generations of nuclear power plant, we developed a method for modelling power-beam welding processes including the prediction of residual stress. We drew on our previous knowledge of weld modelling, to create a method that would enable accurate prediction of residual stresses whilst also being computationally efficient.
To validate our method a number of electron beam welded and laser beam welded specimens were created, state of the art methods were then applied to measure the residual stresses in these specimens. We used these residual stress measurements to validate the predictions from our models for the electron beam welded specimens.
