摘要

A method for manufacturing a welded blank (1), comprising the steps of: - providing two precoated sheets (2); - butt welding the precoated sheets (2) using a butt weld filler wire. wherein the precoating (5) completely covers at least one face (4) of each sheet (2) upon butt welding, wherein the filler wire (20) contains 0.01 wt. % to 0.45 wt.% carbon content, - the composition of the filler wire 20 and the proportion of the filler wire 20 added to the weld pool, such that the weld joint 22 is (a) a quenching factor FT _WJ : where: - FT _BM : the quenching factor of the minimally curable substrate ( 3 ) and - FT _WJ and FT _BM are: FT=128 + 1553xC + 55xMn + 267xSi + 49xNi + 5xCr - 79xAl - 2xNi² - 1532xC² - 5xMn² - the quenching factor, (b) the carbon content, as determined by 127xSi² - 40xCxNi - 4xNixMn, the _{softening factor FA WJ} is FA _WJ > 5000 _{if the carbon content C WJ} <0.15 wt.% or C _WJ ≥ 0.15 wt.%, selected to have the above carbon content, where FA=10291 + 4384.1xMo + 3676.9Si - 522.64xAl - 2221.2xCr - 118.11xNi- 1565.1xC - 246.67xMn.
