| Abstract: | According to the technical need of submerged arc welding for 784 MPa low alloy high strength steel, through analysis and tests about the flux basicity, slag system type and compositions of deposited metal, a alkaline and fluoride type agglomerated flux with high basicity and a CaF 2 MgO CaO Al 2O 3 system is developed. This flux matched with a suitable wire reached the technical need of submerged arc welding for 784 MPa low alloy high strength steel. |
