Characteristics | 1. LC-318NH is an iron powder Extra hydrogen type covered electrode to be used in all-position welding of aluminum-killed steel for low-temperature service and with good crack resistibility. 2. It provides excellent notch toughness at -45℃ and good usability in direct current welding. |
Notes on usage | 1. Pay attention not to exceed heat-input because excessive heat-input causes deterioration of impact values of weld metal. 2. Dry the electrodes at 350-400℃ for about one hour before use. 3. Adopt back step method or strike the arc previously on a small steel piece to prevent blowholes at the arc striking in a groove. 4. Keep the arc as short as possible. |
