XRD and DTA Analysis of Developed Agglomerated Fluxes for Submerged Arc Welding

الملخص EN

A unique study of structural and chemical analysis of crystalline phases in developed agglomerated fluxes was carried out.

Thirty-two fluxes were developed by using a mixture of oxides, halides, carbonates, silicates, and ferroalloys for submerged arc welding.

The present paper focuses on only ten (out of thirty-two) fluxes which were analyzed by X-ray diffraction (XRD) to know the different types of oxides formed and changed in oxidation number of metallic centers after sintering process at around 850∘C.

To know the effect of temperature over phase transformation and melting of different compounds, differential thermal analysis (DTA) was carried out from 1000 to 1400∘C.

This study aims to know the quantity of ions present (percentage) and melting behavior of developed agglomerated fluxes for submerged arc welding process.
