|Title:||Modeling and analysis by response surface methodology of hardness for submerged arc welded joints using developed agglomerated fluxes|
|Keywords:||Response surface methodology;Submerged arc welding;Agglomerated fluxes;Hardness|
|Abstract:||The present study evaluates the hardness of submerged arc welded joints by using developed agglomerated fluxes during submerged arc welding. Response surface methodology (RSM) technique is used to conduct the experiments. Flux constituents MnO, CaF2, NiO, MgO and Fe-Cr are chosen as variables added into the main constituents CaO, SiO2 and Al2O3 to study the performance in terms of hardness. The results identify the most important constituents favoring the hardness are MnO, MgO, NiO and Fe-Cr, where as CaF2 is not so prominent to improve the hardness.|
