Nimotherme-1(Spl) is a low hydrogen, iron powder electrode yielding a tough and ductile weld deposit having 1%Ni - 0.25%Mo. Ideally suited for welding fine- grained and nickel steels for service temperatures down to minus 40°C. Typical applications include storage tanks for liquefied gases like Ammonia, distillers in coke oven batteries and petrochemical industries. Also suitable for welding heavy sections and highly restrained joints subjected to dynamic loading, impact and severe service conditions.
1. Ensure the electrodes are dry. Re-dry the electrodes at 300 C for 2 hours.
2. Restrict the heat input to a minimum during welding to achieve better properties.
