| titleOfInvention | High-strength and high-toughness metal powder type flux-cored wire with no need of being pre-heated before welded |
| abstract | The invention provides a high-strength and high-toughness metal powder type flux-cored wire with no need of being pre-heated before welded. Steel skin is 79-84% of a total weight of a welding wire and a flux core is 16-21% of the total weight of the welding wire. The steel skin is manufactured by using a cold rolling carbon steel strip and comprises the following components: 0.02-0.055% of C, 0.005-0.0085% of Si, 0.15-0.35% of Mn and the balance of iron; and the flux core comprises the following components: 12-18% of nickel powder, 2-4% of manganese powder, 3-7% of silicon iron, 2-6% of ferro-molybdenum, 0.8-2.5% of ferrotitanium, 1-5% of mid-carbon ferromanganese, 0.8-2.5% of potassium fluosilicate and rear earth oxide in sum, and the balance of iron powder. The flux-cored wire provided by the invention has the advantages of good welding process, high melting efficiency and less slag quantity; the yield strength of deposited metal can be more than 590 MPa; the impact rigidity at a temperature of -50 DEG C can be more than 70J; and the diffusible hydrogen is in an ultralow hydrogen level. |
