What is Slag? (with pictures)
Oct 01, 2019· Non-ferrous smelting, used to refine copper, lead, and similar metals, produces highly ferrous slag, as iron is an undesired element. Ferrous smelting, such as that used to produce steel, creates non ferrous slag, as all the iron is used in the smelting process. After slag is allowed to age, it can be sold for use in other industrial processes.Get Price

What is Arc Welding? - Definition and Process Types - TWI
Electro-Slag Welding (ESW) A vertical process used to weld thick plates (above 25mm) in a single pass. ESW relies on an electric arc to start before a flux addition extinguishes the arc. The flux melts as the wire consumable is fed into the molten pool, which creates a molten slag on top of the pool.Get Price
