This report describes properties of deposit metal for making submerged-arc wdlding with domestic bonded fluxes for mild steel and high tensile steels up to 60kg/(mm)^2. It is shown that impact test results at low temperature with bonded fluxes are far superior to ones with fused fluxes. (1) Filler wire contained one percent manganese is better than the others to weld mild steel. Impact values with deposit metal are 6kg-m/(cm)^2 at -70℃ with 650℃ one hour stress relief. Then those values are 21kg-m/(cm)^2 as weld and 30kg-m/(cm)^2 stress relief at room temprature to use bonded fluxes for mild steel. (2) With high tensile steels, mechanical properties are good according to combination of filler wires and bonded fluxes to obtain chemical component of deposit metal Mn-Mo type to 55kg/(mm)^2,and Mn-Ni-Mo type to 60kg/(mm)^2. And the effect of manganese deoxidizing from bonded flux is remerkable.
