METHOD FOR MANUFACTURING COLD-ROLLED, WELDED STEEL SHEETS, AND SHEETS THUS PRODUCED

then the welded joint (S1) is removed so as to obtain at least two intermediate cold-rolled sheets. Then the two intermediate cold-rolled sheets are butt welded, so as to create a welded joint (S2), the direction of which is perpendicular to the direction of hot rolling, then the assembly of the at...

Zusammenfassung:	then the welded joint (S1) is removed so as to obtain at least two intermediate cold-rolled sheets. Then the two intermediate cold-rolled sheets are butt welded, so as to create a welded joint (S2), the direction of which is perpendicular to the direction of hot rolling, then the assembly of the at least two intermediate cold-rolled and welded sheets is cold-rolled, in a step (L2), to the final thickness ef, the direction (DL2) of the cold rolling step (L2) coinciding with the direction of rolling (DL1).
