Experimental study was made on the effect of alloying elements on brittle fracture characteristics of submerged-arc welded joint, empolying 120 mm width tensile specimen.
Steels containing higher amount of manganese, chromium and nickel have better fracture characteristics than steels with lower content.
The important findings in this study are in the fact that small amount of titanium, zirconium and aluminium are effective in improving weld bond fracture characteristics. Suitable content of titanium and zirconium are 0.02 % and 0.05 %, respectively.
