Modelling of manufacturing processes

Modelling of joining processes

  • Arc welding
  • Beam processes (Electron Beam, Laser)
  • Friction welding
  • Friction stir welding (FSW)
  • Low stress no distortion
  • Laser welding of plastics
  • Brazing (metals, ceramics, electronic components)

Modelling of manufacturing processes

  • Jigging and fixtures
  • Weld sequencing
  • Post weld heat treatment
  • Pressure test

Outputs

  • Residual stresses, distortion
  • Microstructure, phase change
  • Hydrogen content
  • Transient temperatures, strains, stresses
  • Material flow (in FSW)

Benefits of manufacturing process modelling

  • Virtual welding: optimisation of welding parameters to control levels of residual stress and distortion
  • More accurate residual stress values
  • Ability to evaluate welding on new materials and new processes
