Welded steel sheets, and sheets thus produced

A steel sheet that is welded and then cold rolled to a thickness between 0.5 mm and 3 mm, the deformation ratio created by cold rolling in the base metal is equal to εMB, for which the deformation ratio created by the cold rolling in the welded joint is equal to εS, where:0.4≤ɛSɛ⁢M⁢B
