Zusammenfassung:	The present invention relates to a method for the manufacture of a welded joint comprising 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 comprising a titanate and a nanoparticulate oxide selected from the group consisting of TiO2, SiO2, ZrO2, Y2O3, Al2O3, MoO3, CrO3, CeO2, La2O3 and mixtures thereof. La présente invention concerne un procédé de fabrication d'un joint soudé comprenant les étapes successives suivantes consistant : I. à fournir au moins deux substrats métallique, au moins un substrat métallique étant un substrat en acier, et II. à souder lesdits deux substrats métalliques à l'aide d'une tête de soudage tout en appliquant, simultanément, sur lesdits deux substrats métalliques, en avant de la tête de soudage, un flux de soudage comprenant un titanate et un oxyde nanoparticulaire choisi dans le groupe consistant en TiO2, SiO2, ZrO2, Y2O3, Al2O3, MoO3, CrO3, CeO2, La2O3 et leurs mélanges.
