Post-weld cleaning procedures

The influence of different post weld cleaning parameters, such as time, temperature and concentration, will
be studied to find the optimum values for removing weld oxides and restore corrosion resistance.
The study will be performed on four different techniques:
  • Mechanical processes: a) polishing; b)soft grinding + polishing
  • Chemical processes: a) pickling paste; b)acid bath
Additionally a screening LCA analysis in a cradle to grave perspective of the post weld treatments will be carried out
using SimaPro software in order to compare the environmental impact of each different treatment.
