How to weld through mill scale

You can use SMAW or stick welding to weld through mill scale because the electrodes have deoxidizers and a slag system Some stick electrodes are designed to offer better success when welding extremely thick scale or on very dirty base material When you are welding moderate mill scale any stick electrode is a good choice Common AWS stick electrode classes are E6010 E6011 E6013

Mill scale separation – Nordic Water

Mill scale forms during steel production It is a thin oxide coating that is created when steel is hot-rolled When the steel is cooled down with water during the rolling process the mill scale breaks off The cooling water is re-used over and over again which means that mill scale and oil residue particles need to be separated off Mill scale often also contains valuable alloying elements

Mill Scale – IspatGuru

Removal of mill scale is virtually impossible by hand It is extremely tedious and time consuming using power tool cleaning methods Neither of these two methods gives a good base to start Steel from the hot rolling mills has no surface profile which is most important to the overall adhesion strength and integrity of the coating system Mill scale is normally removed from steel surface by

Vinegar for Mill Scale Removal
