SUPERHIGH STRENGTH GAS SHIELDED WELDING WIRE AND METHOD FOR MANUFACTURING THE SAME |
| 摘要 |
Disclosed is a superhigh strength gas shielded welding wire, the contents of chemical elements of the superhigh strength gas shielded welding wire in percentage by mass being: C 0.06-0.12%, Si 0.55-0.80%, Mn 1.60-1.95%, 0<Cu≦0.20%, Cr 0.10-0.35%, Mo 0.10-0.50%, Ni 1.00-1.60%, Ti 0.01-0.20%, B 0.0005-0.0060%, and the balance being Fe and other inevitable impurities. Accordingly, further disclosed is a method for manufacturing the welding wire. The welding wire of the present invention has a low alloy content and a low carbon equivalent, and a weld metal formed by welding with the welding wire has all of a higher strength, a greater low-temperature toughness and a better plasticity, with a good compatibility between the three properties. The weld metal formed by welding using the welding wire further has a good crack resistance and a good welding property. |
