How to weld through mill scale - The Fabricator
Before we talk about welding through it, its important to know exactly what mill scale is. The term hot-rolled steel comes from the manufacturing process. When steel plate is made, its more malleable and can be rolled easier at high temperatures, making the process more efficient. As the hot material encounters oxygen, an oxide layermill scaleforms on the surface. During welding, mill scale hinders the flow of the liquid welSee more on thefabricator chemistry of fe410 Plasma weldingHow is the Interpass temperature determined in welding?Heating may be continued during the welding process, but frequently the heat from welding is sufficient to maintain the desired temperature without a continuation of the external heat source. The interpass temperature, defined as the base metal temperature between the first and last welding passes, cannot fall below the preheat temperature.See all results for this questionHow Welding Works | HowStuffWorksMar 24, 2009 · Welding, on the other hand, cuts out the middleman and joins the original pieces directly to each other.
