The invention provides a filling flux welding wire, which possesses the advantages of high temperature resistance of the primary layer welding part, which is welded by a single layer joint of the steel plate formed by the soft steel and the high tension steel, and welding operation performance as well as the welding metal machinery performance of the integral gesture welding. The invention is a filing flux welding wire used for the welding of the steel plates formed by the soft steel or the high tension steel and of the filling flux welding wire formed by filling the flux in the steel outer skin. The invention is characterized in that the required volume of the welding flux filling rate is a welding wire integral quality, and compared to the required volume of the welding wire integral quality, the invention comprises C, Si, Mn, Ti, TiO2,A1, A12O3,B,N,Ni(including0%), Cu(including0%), and the invention satisfies the equation that 10 equal to or larger than (Ni+14*C+0.29*Mn+0.30*Cu)/(1.5*Si) larger than or equal to 2.5(symbol of element represents the content of the element (mass percent)). |
