Coated Rod for Soft Steel to 550 MPa Grade Steel Z-43F
Horizontal and downward fillet welding for shipbuilding, bridge building, buildings, and general structures. The fume volume is reduced by approximately 30% compared to similar bars. An exceptional performance is demonstrated by either manual welding or gravity welding. Excellent pit resistance and re-arc properties; slag peels off almost by itself, and the bead surface is glossy and beautiful.

|---|---|---|---|---|---|
| JIS Standard | Z3211 E4340 | Compatible Material Type | For low fume, fillet welding | Amount Of Content | 1 Box (20 kg) |
| Mass(g) | 20000 | Application and Usage Characteristic | Horizontal and downward fillet welding for shipbuilding, bridge building, buildings, and general structures. The fume quantity is reduced by about 30% when compared to similar rods. Exhibits excellent performance in both manual welding and gravity welding. Excellent pit resistance and re-arc properties; slag peels off almost by itself, and the bead surface is glossy and beautiful. | Main Points of Work | Suitable currents will differ based on welding methods, the state of steel plates, etc. Pay attention to the state of slag and adjust it. The electrode manipulation ratio can be between 0.8 and 1.6. However, 1.2 to 1.5 is considered best for gravity welding. Excessive moisture absorption may lead to undercutting, the unevenness of beads, etc. Please dry at temperatures between 70°C and 100°C for 30 to 60 minutes. Excessive drying (such as that caused by long periods of time or high temperatures) may lead to incomplete penetration and burnt bars, even if no changes in quality are apparent. |
