| Characteristics | LC-318N is an iron powder-low hydrogen type covered electrode to be used in all-position welding of aluminum-killed steel for low-temperature service. It provides excellent notch toughness at -45℃ and good usability in direct current welding. |
| Notes on usage | (1) Welding heat input must be controlled in order to get required impact value, since notch toughness tends to be decreased by excessive heat input. (2) Preheating at 50~100 is needed depending upon the kind of steel and its thickness. (3) Dry the electrodes at 350~400℃ for about one hour before use. (4) Adopt the backstep method or strike the arc previously on a small steel piece to prevent blowholes at the arc striking in a groove. |
