Electrodes for Low Temperature Service

Low hydrogen iron powder electrode depositing 3.5% Ni in weld metal. Easy to operate in all conventional welding positions. Radiographic quality welds o possesses excellent toughness even at sub-zero temperatures down to minus 101°C. Ideal suited for welding fine-grained and Nickel steels. Typical applications include pressure vessels, piping, valves, and tanks used for storage, transportation, and distribution of liquefied gases.

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

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

2. Ensure the electrodes are dry. Re-dry the electrodes at 250-300°C for one hour.
