Welding slag is a form of slag, or vitreous material produced as a byproduct of some arc welding processes, most specifically shielded metal arc welding (also known as stick welding), submerged arc welding, and fluxcored arc welding. Slag is formed when flux, the solid shielding material used in the welding process, melts in or on top of the weld zone. Slag is the solidified remaining flux

· Slag inclusions do not contribute to the strength or protection of metals one after being welded. It is necessary to remove them, as it is waste inside the weld metal. Its removal is necessary as it will inhibit the inspection of the weld area, will have a bad visual appearance, will need to be removed in case a second layer or pass is required, and lastly to clean and clear the surface for

· Ferrous slag is currently underutilized. Although the construction industry does use some slag as an aggregate, most is simply discarded. However, slag could be used to treat acid soils or acid mine drainage. Doing so would both offset the cost of restoring abandoned mine areas, as well as decrease steel manufacturers'' current waste footprint.

Slag is a byproduct formed during the manufacturing of steel. In Blast Furnace Slag, calcium sulfide is a predominant impurity that results in environmental concerns, specifically when used for trails, road beds and embankments. The calcium sulfide leaches from the slag and results in a greenish/yellow liquid runoff that has an aesthetically undesirable odor and color, and could cause

Steelmaking is the process of producing steel from iron ore and/or steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel.

Other uses and dangers We are aware that steel slag aggregate has been successfully used in a variety of other applications by specialist contractors. For example, it has been used as stone column ground stabilisation and as a raw feed in the cement manufacturing process. In applications other than road construction, we however cannot advise on the suitability of using steel slag aggregate. It

Slags from the Iron and Steel Industry. Background With world steel production now well over a billion tonnes per year, the slag that arises from some of the processes involved is a major resource. Traditionally it has been used mainly as an aggregate but for some types there are other applications, such as a raw material for cement or as a fertiliser. Slag, as the term will be used here, is

The slag is named according to the furnace in which it''s created, and you have to refine iron ore in a blast furnace in order to make steel. Steel furnace slag would be called BOF or EAF slag, and is little different from Orcem''s blast furnace slag in composition — except that it''s likely cleaner, since the steel furnaces use refined iron from a blast furnace along with 1020 percent

Steel slag is the ideal material for unpaved parking lots or driveways. Steel slag properties include high angularity that provides stability, heavy unit weight to stay in place and "free lime" that provides for a weak cementing effect aiding compaction and is ideal for areas prone to heavy truck traffic.
