Chemical And Structural Characterization of the Amorphous Phases in Fused Fluxes for Submerged-Arc Welding

A study of chemical and structural characterization of fused fluxes for submerged-arc welding was conducted. Two flux formulations were prepared using mineral oxides for fusing processes. The micro-morphology and chemical composition of fused flux was compared by using the methods of Chemical analysis and scanning electron microscope (SEM)/Energy Disperse Spectroscopy (EDS) analysis. The phases of two fluxes were analyzed by X-ray diffraction (XRD) to determinate type of amorphous formed. This kind of flux characterization enables us to quantify the ions that might be present in the plasma arc during the submerged welding process due to the fluxes. This analysis is also possible the prediction of reactions in the weld pool.
