Abstract
The butt welding process of two steel sheets includes the steps of: - providing two steel sheets having a composition such that the gamma factor of the unmodified target weld bead composition is strictly greater than 0.39, - butt welding these by laser with an additional material incorporated into the weld such that the gamma factor of the modified target weld bead composition is less than or equal to 0.39, Gamma = C + Si / 30 + Mn / 20 + 4.8*P + 4*S-AI / 20.
