| Amount Of Content | 1 Box (5 kg x 4 Cases) | Mass(g) | 5000 | Features | A low hydrogen system all position welding rod for 490 MPa grade high tensile strength steel. Excellent crack resistance for welded metal, good mechanical properties and X-ray performance. In particular, the upright, upward posture is also very easy to use. A representative brand for traditional low hydrogen type welding rods. |
| Application | Welding of 490 MPa class high tensile steel (SM490, SM490Y, SM520, etc.) used in important structures for shipbuilding, construction, bridge building, and pressure vessels, etc. | Main Points for Welding Construction | Dry the welding rod for about 60 minutes at 300 to 350°C before use. To prevent the formation of blow holes or pits, use a backstepping rod during arc generation. Also, keep the arc length as short as possible during welding. Water droplets, rust, oils and fats inside the groove may cause cracks or blow holes, so thoroughly remove them. | Example of Deposited Metal Chemical Composition C(%) | 0.07 |
