Modelling of Interface Evolution in Advanced Welding (MintWeld)

Connect, no. 163, November/December 2009, p.3

TWI is a partner in a new Framework 7 project which began recently. The project is led by Leicester University and 11 partners are involved from seven EU countries.

The work will establish the capability to design and engineer welding processes with a multi-scale, multi-physics computational modelling approach. An integrated suite of modelling software will be developed and validated which will be able to describe the key phenomena of the welding process at all relevant length scales. Special emphasis will be given to: evolution of the solid-liquid interface, including the description of macro-scale mass flow and thermal profiles; meso-scale solid/liquid interface motion; micro/nano-scale grain boundary and morphology evolution; mechanical integrity; and service life performance of the welded product.

This project aims to deliver an accurate, predictive and cost-effective tool that will find widespread application in a range of European industries in order to provide a new capability for intelligent design of high performance welded systems and interfaces. This will enable novel markets of high economic and strategic importance to be penetrated by European companies.


The European Commission will contribute ?3.55m to this ?4.8m four-year project. TWI will:

  • Provide other team members with up to date information on the most pressing industry needs regarding dissimilar metal welding and define relevant testing methodologies under representative in-service conditions
  • Characterise dissimilar metal interface microstructures and diffusion during PWHT both experimentally and via thermodynamic simulation
  • Conduct environmental mechanical testing to validate the model generated by the modelling teams
  • Disseminate and exploit the knowledge and tool package developed through the project within its Industrial Membership network
