Welding Slag

Thanks for your info Tommyjoking, but the slag came from Submerged Arc Welding as you know it generates a huge amount of slag. In history, we normally crushed the slag to consider as Recovered, mixed it with Flux (25% Recovery and 75% ) and used it in production, but we stop that practice due to Customer requirements and related quality issues.

Consumables Corner: The differentiating factors in SAW flux

SAW flux plays several roles during the welding process. It provides arc enhancers, produces shielding gas, protects the weld from the atmosphere, assists in bead shape, deoxidizes the weld puddle, and some even add alloy to the weld metal. Flux is manufactured by one of three methods known as fused, agglomerated or bonded, and mechanically mixed.

What is Submerged Arc Flux? - Welding Ovens by Keen

In Submerged Arc Welding (SAW), the granular flux provides a blanket over the weld, which protects against sparks and spatter. In SAW, the granular flux is frequently the means for achieving high deposition rates. The flux is also instrumental in producing the type of quality weld that is common in this particular welding process.
