Chosun Welding
Chosun LC-318 High Tensile Steel Welding Rod
Welding of 50kgf/mm2 class high tensile strength steel of ships, bridges and pressure
vessels.
| Classification | AWS A5.1 E7018 |
| Applications | Welding of 50kgf/mm2 class high tensile strength steel of ships, bridges and pressure vessels. |
| Characteristics | LC-318 is iron powder low hydrogen type electrode for all-position welding. Its usability is the best with direct current application as well as alternating current application. |
| Notes on usage | (1) Dry the electrodes at 300~350℃ for 30~60 minutes before use. (2) Adopt back step method or strike the arc on a small steel plate prepared for this particular purpose to prevent blowholes at the arc starting. (3) Keep the arc as short as possible. |
