A low hydrogen iron powder electrode depositing 2.5% Ni steel weld metal. Easy to operate in all conventional welding positions. Radiographic quality welds possesses excellent toughness even at minus 60°C. Ideal for welding fine grained and Nickel steels. Typical applications include containers and piping systems and tanks used for storage, transportation of liquefied propane and butane, A&P brackets etc.
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 300°C for 2 hours.
