This experimental study was conducted to evaluate the effects of CaF2, FeMn and NiO additives on impact strength and hardness of low carbon steel plate welds using submerged arc welding. Fluxes containing CaO, SiO2 and Al2O3 as base fluxes were designed and developed through agglomeration technique. CaF2, FeMn and NiO were added to these fluxes in the varying amounts of (2–8) %.
