Abstract
A welded blank includes a first pre-coated steel sheet, a second pre-coated steel sheet the first pre-coated steel sheet including a principal first face and an opposite principal first face, the first layer being removed by melting and vaporization in a first peripheral zone of the first pre-coated steel sheet, and the second pre-coated steel sheet including a second principal face and an opposite second principal face, the second layer being removed by melting and vaporization in a second peripheral zone of the second pre-coated steel sheet. At least one welded joint defining a median plane perpendicular to the first and second principal faces. The welded joint area has at least one advantageous characteristic such as a sum of the widths of the first and second peripheral zones of the first and second pre-coated steel sheets varying by less than 10% along the welded joint, the first and second solidification ripples being aligned at the welded joint with respect to the median plane, morphologies of the first and second solidification ripples at the welded joint being identical and symmetrical, and/or an aluminum content in the welded joint being below 0.3%.
