| Characteristics | LC-700 is low hydrogen type electrode for all-position welding. Its usability and X-ray soundness are very good. It provides weld metal of good notch toughness and of high crack resistibility. |
| Notes on usage | (1) Dry the electrodes at 350~400℃ for about one hour before use and store the electrodes at 100~150℃ after drying them with attention to keep away from moisture. (2) Adopt back step method or strike the arc on a small steel plate prepared for this particular purpose, because arc striking on base metal is in danger of initiating cracking. (3) Keep the arc as short as possible. (4) Preheat at 100~150℃. The temperature to be applied varies in accordance with plate thickness and kind of steel to be welded. (5) Pay attention not to exceed proper heat-input because excessive heat-input causes deterioration of impact values and yield strength of weld metal. |
