WebDec 8, 2024 · Slag inclusion on the surface of parts diminishes the quality of the casting surface and can make machining difficult. Slag inclusion in the interior of a cast part has a greater impact on the part’s structural characteristics. Internal slag inclusion reduces tensile strength and makes a part more likely to fracture. Preventing Slag Inclusion WebAs slag is the residue of the flux coating in MMA welding, it is principally a deoxidation product from the reaction between the flux, air and surface oxide. The slag becomes trapped in the weld when two adjacent weld …
