Optimising Weld Process Conditions for Enhanced Fatigue Performance

Abstract:

This paper presents some ideas on incorporating output from advanced synchrotron and neutron scanning strain methods in improved assessment of the influence of weld process parameters on residual strains at welds and on their fatigue performance. It very briefly outlines two different cases involving synchrotron diffraction strain scanning of friction stir welds in a strain hardened aluminium alloy and neutron diffraction strain scanning of MIG welds in high strength steel.
