Abstract
(EN)
A welding wire for submerged arc welding of high-manganese low-temperature steel, and a welding method. The chemical compositions and mass percentages of the welding wire are as follows: C: 0.2%-0.4%, Mn: 12%-15%, Ni: 16%-20%, Cr: 2%-5%, P ≤ 0.004%, S ≤ 0.002%, with the balance being Fe and inevitable impurities.
(FR)
L'invention concerne un fil de soudage pour soudage à l'arc submergé d'acier basse température à haute teneur en manganèse, et un procédé de soudage. Les compositions chimiques et les pourcentages en masse du fil de soudage sont les suivants : C : de 0,2 % à 0,4 %, Mn : de 12 % à 15 %, Ni : de 16 % à 20 %, Cr : de 2 % à 5 %, P ≤ 0 004 %, S ≤ 0 002 %, le reste étant du Fe et des impuretés inévitables.
