Aluminum ash is the scum and slag floating on the upper layer of the molten aluminum during the metallurgical melting process of electrolytic aluminum, cast aluminum, and recycled aluminum. Aluminum ash (slag) is mainly composed of metal aluminum and non-metal oxides, of which aluminum oxide usually accounts for more than 60%, and other oxides ...

Iron and steel slags are coproducts of iron and steel manufacturing. In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent. The iron ore is a mixture of iron oxides, silica, and alumina. From this and the added fluxing agents molten slag and ...

Any welding procedure must take into account the chemical composition and mechanical properties of the base metal. Metal tests enable us to identify a metal, and establish its properties. When the behaviour of metal is known, then a compatible filler metal can be chosen, and the right welding procedure be devised.
