Description:

Weld profile can have a profound influence on the performance of welds in service. Welds are rarely subjected to a single loading regime and cylinderical components (such as shafts) often experience combined cyclic and torsional stresses. This project will use a new test rig to investigate the influence of weld profile on the performance of components in mixed stress regimes. The aim of the work is to develop guidelines on weld finishing for critical applications.
