How and why alloying elements are added to aluminum
The most common appliions for the 1xxx series alloys are aluminum foil, electrical buss bars, metallizing wire and chemical tanks and piping systems. The addition of alloying elements to aluminum is the principal method used to produce a selection of different materials that can be used in a wide assortment of structural appliions.
Gas metal arc welding
A related process, flux cored arc welding, often does not utilize a shielding gas, instead employing a hollow electrode wire that is filled with flux on the inside. Development The principles of gas metal arc welding began to be developed around the turn of the 19th century, with Humphry Davy ''s discovery of the electric arc in 1800.
Calcium Silicon | Miller and Company
13/5/2008· The most widely used method for intergrated steel appliions is in the form of cored wire. This is mainly because calcium has a low density and high reactivity in the ladle making it difficult to introduce and retain in the melt.
Welding - Wikipedia
This cored wire is more expensive than the standard solid wire and can generate fumes and/or slag, but it permits even higher welding speed and greater metal penetration.  Gas tungsten arc welding (GTAW), or tungsten inert gas (TIG) welding, is a manual welding process that uses a non-consumable tungsten electrode, an inert or semi-inert gas mixture, and a separate filler material. 
Barcast™ 90 Deoxidiser | Asmet
Description: Barcast 90 is used as a potent de-oxidising pre-conditioner for Ductile Iron production. The efficiency of the treatment process is improved, leading to a reduction in alloy consumption and slag generation. This type of pre-conditioner is usually added to

The main advantage for the cored wire process is the option of treating high sulphur base iron directly without a separate desulphurizing addition. The tundish cover process will be most efficient if base iron sulphur is restricted to maximum 0.03% S. Closely connected to sulphur removal is the inoculation effect from the treatment process.
METALLURGY FOR INSPECTION PERSONNEL
Alloying elements may be added through the addition hopper. If deep desulfurization is required active desulfurizing agents Ca, Mg, CaSi are injected into the melt through the injection lance or in form of cored wire. Besides refining operations Ladle Furnace

In addition to deoxidation vacuum treatment helps to remove Hydrogen dissolved in liquid steel. Hydrogen diffuses into the CO bubbles and the gas is then evacuated by the vacuum pump. Movement of the molten steel caused by CO bubbles also results in refining the steel from non-metallic inclusions, which agglomerate, float up and are absorbed by the slag.

As such, 50 pounds of flux-cored wire compared to 50 pounds of stick electrodes would yield a higher deposition efficiency: more of the filler metal is actually deposited into the joint. That efficiency ranges from 75-83 percent with this particular wire compared to 65-73 percent with a 7018 stick electrode (when the product has been burned to a 2-inch stub).
