ABSTRACT: Addition of nano size particles of TiO2 in the coating of shielded metal arc welding electrode (E 11018M) partially substituting the conventional micro size TiO2 was studied for possible enhanced electrode characteristics. The results show that the nano size particle of TiO2 improved recovery of elements such as Mn, Ni, Mo, Ti etc. as well as increased all-weld-metal tensile and charpy impact properties at –51℃. Furthermore, the charpy impact properties were found to be very sensitive to variations in Ti content of the weld deposit.
