Arc welding modelling

Research summary

Metal welding is important in the manufacture of rolling stock, with the use of software that reliably predicts weld properties having the ability to save significant time and expense. CSIRO has developed modelling software that can provide critical information on a weld, including depth and shape of the weld and temperature distributions in the welded metal. This project developed a software module to use for welding rail components.

Start/end date

1 April 2018 to 31 March 2020

Total contracted budget (including in-kind)

$1,810,902

Key achievements

  • A software module was developed for predicting welding parameters that give optimised quality and speed of welds in rail components.
  • Graphs showing weld cross-sections, and slice and surface views of the weld in progress, were built into the software module.
  • Validated models for arc welds for aluminium, magnesium and steel joints for butt, lap, T- and corner joints were developed and incorporated into the software module.
  • Validated models for arc welding of steels with Ar/O2 and Ar/CO2 shielding gas were developed and incorporated into the software module.
