Détails
Conçu pour des taux de dépôt très élevés et une résistance accrue au craquage d’hydrogène et à la porosité sur l’acier contenant du soufre ou des contaminants. Recommandé pour le soudage en un ou plusieurs passages sur l’acier au carbone et certains aciers faiblement alliés dans des applications sans exigences de résistance aux chocs.
Traits
- Taux de dépôt très élevés
- Augmentation de la résistance au craquage d’hydrogène et à la porosité
- Arc doux et peu pénétrant pour un mélange minimal de matériau de base
