In any welding process it is desirable to use modeling to reduce the time for processoptimisation and increase the amount of process innovation. Ideally the model wouldtake input process parameters and produce outputs in terms of joint performance. Thisrequires an integrated modelling approach incorporating coupled process, materialresponse and material performance models. This paper provides details of how this isbeing implemented for use in friction stir welding for application to aerospace structures.Currently the process model is a dynamic coupled fluid flow thermal model. Thematerial response models comprise microstructural and residual stress models. Thematerial performance models are targeted at mechanical properties, corrosion behaviourand fatigue performance. The paper highlights the state of development of each of thesub models and the degree of coupling together that has been achieved. |
