Abstract Scope |
In this talk, I will present our work in an EU FP7 project (MintWeld) which I collaborated with Jon. In the project, we established a multi-scale, multi-physics modelling frame work for arc welding. An integrated suite of modelling software has been developed and validated, able to describe the key phenomena of the welding process at all relevant length scales, with a special emphasis on in-situ measurement of internal flow in melt pool during arc welding, the solid-liquid interface evolution, including the description of macro-scale mass flow and thermal profile in weld pool, meso-scale solid/liquid interface movements during melting and solidification of weld joints, micro/nano-scale grain boundary and morphology evolution in the solidified joints, mechanical integrity, and service life of the welded products.
