Some of those challenges include the presence of chromium oxide how to manage heat input choosing which welding process to use dealing with hexavalent chromium and how to finish it properly. Stainless steel creates strong welds with other stainless steel and. The effect of various single component fluxes and a multi-component flux on weld bead geometries was analysed.
It has different composition and is typically several orders of magnitude thicker than the 24nm thick passive film naturally established in oxidising environments on stainless steels.
As the steel structure changes through melting the free iron particles begin to accumulate on the surface where they react with oxygen and cause corrosion.
