Weld Slag Clean Up Requirements… | American Galvanizers ...

Sep 16, 2015 · Chemical cleaning solutions used in the galvanizing process cannot remove weld flux and slag. Therefore, weld slag must be removed by grinding, abrasive blast cleaning, wire brush, flame-cleaning, or chipping. In order for weld slag to develop, flux must melt from the flux-coated welding wire/stick, then deposit onto the weld area.Some results are removed in response to a notice of local law requirement.
