Abstract

Se proporciona una junta soldada con excelente resistencia al agrietamiento por soldadura. Una junta de soldadura se obtiene soldando placas de acero resistentes al desgaste con una dureza superficial de 400 HBW o mas en terminos de dureza Brinell. Durante la soldadura, las placas de acero a soldar, el material de soldadura, las condiciones de soldadura y similares se ajustan de modo que una pieza de metal de soldadura tenga una composicion que contenga, en % en masa, C: 0,20 % a 0,80 %, Si: 0,10 % a 0,90 %, Mn: 15,0 % a 28,0 %, P: 0,030 % o menos, S: 0,030 % o menos, Ni: 0,01 % a 10,00 %, Cr: 0,4 % a 1,9 % y Mo: 0,01 % a 5,00 %. De esta manera, se puede producir una junta soldada sin precalentamiento o poscalentamiento mientras se previene la aparicion de grietas en la soldadura.
