Abstract

L'invention concerne un procédé de fabrication d'un joint soudé, qui permet d'obtenir une excellente résistance au pelage même lorsqu'un matériau à haute résistance est utilisé en tant que matériau à traiter. Le procédé de fabrication d'un joint soudé comprend : une étape de préparation permettant de préparer un matériau à traiter, le matériau ayant deux plaques métalliques chevauchées et une partie métallique de soudure permettant de joindre les deux plaques métalliques ; et une étape d'irradiation permettant d'irradier, avec un laser, le matériau à traiter, dans une condition satisfaisant une relation prescrite.
