Electrodes for Low Temperature Service

* Low hydrogen electrode depositing 2.8%Ni and 0.3%Mo weld metal. * Pleasing operating characteristics. * Weld metal of radiographic quality

Ideally suited for welding grain refined steels and nickel steels for service temperatures down to minus 50°C. Typical applications include storage tanks for liquefied gases like Ammonia, distillers in coke oven batteries, petrochemical industries, DMR 249B (AB2) steel, etc. Also suitable for welding heavy sections and highly restrained joints subjected to dynamic loading, impact and severe service conditions.

1. For best impact properties, accomplish minimum heat input by:

* Using smallest size of electrode possible. * Minimum weaving. * Proper control over inter pass temperatures. * Maximum number of layers. * Welding in down hand position wherever possible.

2. Ensure the electrodes are dry. Re-dry the electrodes at 480°C for one hour.
