ABSTRACT:
A granular flux suitable for submerged arc electric welding comprising particles of composite fluxing ingredients of the agglomerated or fused type combined with a halogenated polymer as a reducing agent for diffusible hydrogen in the resulting weld metal and a method of making this granular flux wherein the polymer is mixed with the flux particles and then heated to a temperature above the melting temperature of the polymer and below the vaporization temperature of the polymer.
