A low hydrogen electrode yielding a tough and ductile weld deposit having 1% Ni- 0.25% Mo suitable for welding fine-grained and Ni steels for service temperatures down to minus 60°C. Typical applications include storage tanks for liquefied gases, distillers in coke oven batteries and petrochemical industries. Ideal for welding high strength and fine-grained steels subjected to sever dynamic loading and sub-zero temperature service.
1. Ensure the electrodes are dry. Re-dry the electrodes at 250-300 C for one hour.
2. Restrict the heat input during welding.
