Abstract

La présente invention se rapporte à un joint soudé par points d'au moins deux tôles d'acier, au moins l'une des tôles d'acier présentant une limite d'élasticité supérieure ou égale à 600 mpa, une résistance ultime à la traction supérieure ou égale à 1 000 mpa, un allongement uniforme supérieur ou égal à 15 %. La composition chimique de métal de base comprend 0,05 = c = 0,21 %, 4,0 = mn = 7,0 %, 0,5 = al = 3,5 %, si = 2,0%, ti = 0,2 %, v = 0,2 %, nb = 0,2 %, p = 0,025 %, b = 0,0035 %, et le joint soudé par points contient une microstructure de zone fondue qui contient une quantité d'aluminium (al) supérieure à 0,5 % et qui contient une fraction superficielle de zones isolées inférieure à 1 %, lesdites zones isolées étant des zones supérieures à 20 µm
