Why could a single SA welding flux have more than one AWS classification?

To determine

Thereason that single Submerged Arc Welding has more welding flux than that of AWS classification.

Explanation

Submerged Arc Welding is a welding process used for the joining of similar as well as dissimilar metals.The arc is produced between the electrode and workpiece which is further used for the fusion of these metals.The fusion forms a molten pool and is protected by using a thick layer of flux or slag from the atmosphere. This molten flux or slag is formed by the granular fluxing.

This may be the reason that it has more welding flux than that of AWS specification. The slag prevents the molten metal to react with the contaminants of air, and hence gives a good quality of weld.

The classification of fluxes is done based on mechanical properties of the deposited weld metal. The classification of flux is prefixed with the alphabet F which defines that it is a flux
