The present study has been undertaken to evaluate the basicity concept of oxygen content estimation subject submerged arc welded metal. investigated fluxes cover a wide range indices from 0.31 19.00 at full coverage with acidic, neutral, and basic fluxes. metal (flux potential) is predicted by employing traditional flux index models CALPHAD technique (gas–slag–metal equilibrium model). It revealed that gas–slag–metal model in this capable remedying shortcomings respect predicting potentials...
Manganese is a vital element in determining the mechanical properties of submerged arc welded metal. To ensure reliable weld, equilibrium model has been used for decades to predict and control manganese content, particularly when MnO-bearing fluxes are applied. However, only considers chemical interactions within weld pool zone, leading significant inaccuracies. address this limitation, we propose multi-zone that accounts all essential reaction zones process via Calphad technique. The...
Submerged arc welding is a complex metallurgical system involving various phases with temperature higher than 2000 °C. Since the hot weld pool shielded beneath flux, thermodynamic investigation on O content variation during process remains nebulous. Within this framework, approach has been proposed to estimate tendency of in metal overall submerged process. The modeling based assumptions Oxygen Layer Theory, Local Attained Equilibrium, and Scheil Solidification. simulated measured data show...
With the advancement of manufacturing industry, performing submerged arc welding subject to varying heat inputs has become essential. However, traditional thermodynamic models are insufficient for predicting effect input on elemental transfer behavior. This study aims develop a model via CALPHAD technology predict influence essential elements such as O, Si, and Mn when typical SiO2-bearing fluxes employed. The predicted data demonstrate that proposed effectively forecasts changes in behavior...
Neutral Point indicates the flux formula where no transfer of alloying element between and weld metal occurs. For submerged arc welding process, is an essential definition for design specification since it helps to identify microalloying ability. The scientific hypothesis that only a function considered as basis Mitra kinetic model. Within this framework, by performing with CaF2-SiO2-Na2O-MnO agglomerated fluxes under various heat inputs, moving has been captured, indicating proposed in...
From a thermodynamic perspective, the present study has been performed to investigate effect of SiO2 level in agglomerated fluxes on element transfer behavior essential elements, by applying CaF2-Na2O-SiO2 with varying contents.
