| Applications | Welding of 80kgf/mm2 class high tensile strength steel for pressure vessels, penstocks, bridges, offshore constructions, industrial machinery and construction machinery. |
|---|---|
| Characteristics | LC-800 is a low hydrogen type electrode for all-position welding and provide good X-ray soundness, notch toughness and crack resistibility. |
| Notes on usage | (1) Dry the electrodes at 350~400℃ for about one hour before use. Store the electrodes at 100~150℃ after drying, keeping them 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 120~180℃. 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. (6) Immediate post heating at 150~200℃ after welding is effective to prevent cracking. |
