This experiment is very interested in how adding titanium dioxide powder to submerged arc welding on low alloy steel plates affects the bead geometry, grain size, and hardness. The commercial fluxes were combined with powdered titanium dioxide at varying concentrations (2.5%, 5%, 7.5%, 10%, and 12.5%). No changes were made to the welding process parameters despite the variety of welding situations. It has been shown that the inclusion of titanium dioxide significantly improves the bead geometry parameters. The optimal bead shape parameters were found at a titanium dioxide enrichment level of 5%. Titanium enrichment can be linked to amorphous ferrite formation and grain refinement in the microstructure of weld metal (WM). Increases in titanium content tend to cause the ferrite and pearlite phases’ typical grain sizes to reduce. According to a phase study of WMs, as titanium content increased, ferrite percentages rose and pearlite percentages fell. However, the hardness profile of welded parts did not follow a predictable pattern as titanium content was increased. Before mixing TiO2 powder in commercial granular flux, examine hardness, bead shape, and grain size. Use of TiO2 powder combined with commercial flux; welding conditions remain constant. TiO2’s effect on Submerged Arc Welding weld metal was compared with the results to determine an optimal ratio.
