FLUX CORED WIRE FOR GAS-SHIELDED ARC WELDING FOR HIGH TENSILE STRENGTH STEEL, CAPABLE OF MAINTAINING THE STRENGTH OF WELD METAL AND REDUCING THE AMOUNT OF OXYGEN

摘要

PURPOSE: A flux cored wire for gas-shielded arc welding for high tensile strength steel is provided to improve the ductility of a welding part by adding silicon to a steel outer cover and flux and improving the movement of the slag and the outer shape of bead.;CONSTITUTION: A flux cored wire for gas-shielded arc welding for high tensile strength steel consists of C 0.03~0.11 weight%, TiO2 3.0~10 weight%, Mn 1.0~4.5 weight%, Si 0.3~2.0 weight%, B 0.002~0.04 weight%, Ni 0.5~3.5 weight%, Mg 0.1~1.5 weight%, Al 0.01~0.8 weight%, one or more kinds 0.1~1.2 weight% selected among Cr, Mo, and V, and the rest consisting of Fe and impurities.;COPYRIGHT KIPO 2010
