Abstract
A method for the manufacture of a welded joint including the following successive steps: I. The provision of at least two metallic substrates wherein at least one metallic substrate is a steel substrate, and II. The welding of the at least two metallic substrates with a welding head while, simultaneously, applying on the at least two metallic substrates, ahead of the welding head, a welding flux including a titanate and a nanoparticulate oxide selected from the group consisting of TiO2, SiO2, ZrO2, Y2O3, Al2O3, MoO3, CrO3, CeO2, La2O3 and mixtures thereof.

Method for the manufacture of a welded joint comprising the following successive steps:
- providing at least two metallic substrates wherein a first of the at least two metallic substrates is a steel substrate;
- and welding the at least two metallic substrates with a welding head while, simultaneously, applying on the at least two metallic substrates, ahead of the welding head, a welding flux including a titanate and a nanoparticulate oxide selected from the group consisting of TiO2, SiO2, ZrO2, Y2O3, Al2O3, MoO3, CrO3, CeO2, La2O3 and mixtures thereof, wherein the nanoparticles have a diameter between 5 and 60 nm;
- and wherein a diameter of the titanate is between 1 and 40 μm.
