DETALLES
Diseñado para tasas de deposición muy altas y una mayor resistencia al agrietamiento por hidrógeno y a la porosidad en aceros que contienen azufre o contaminantes. Recomendado para soldadura de una o varias pasadas en acero al carbono y algunos aceros de baja aleación en aplicaciones sin requisitos de resistencia al impacto.
Características
- Tasas de deposición muy altas
- Mayor resistencia al agrietamiento por hidrógeno y a la porosidad
- Arco suave y de baja penetración para minimizar la dilución con el material base
