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.

The first digit, the letter 'F', identifies the consumable as a submerged arc welding flux, the next letter 'S' is only included if the flux is made from or includes crushed slag. Omission of this letter 'S' indicates that the flux is unused and contains no crushed used flux introduced either by the flux manufacturer or the welding fabricator.

BAKING AND HANDLING CONDITIONS - Welding Material

4 Slag and metallic particles should be removed from the recycled flux and discarded prior to using recy cled flux. 4 Fines should be removed from recycled flux. Excessive levels of fines will impair the welding perform ance of the flux and degrade the weld bead appearance. 4 Re-crushed slag should not be used as flux for welding operations.

(4) Weld pad obtained using pure slag A weld pad was designed using crushed slag. The spectroanalysis of weld pad was performed to evaluate weld specimen composition.

Slag (welding) - Wikipedia

Welding slag is a form of slag, or vitreous material produced as a byproduct of some arc welding processes, most specifically shielded metal arc welding (also known as stick welding), submerged arc welding, and flux-cored arc welding.Slag is formed when flux, the solid shielding material used in the welding process, melts in or on top of the weld zone (also known as Dross).
