Cast iron is made by re-melting pig iron, often along with substantial quantities of scrap iron and scrap steel and taking various steps to remove undesirable contaminants. Phosphorus and sulphur may be burnt out of the molten iron, but this also burns out the carbon, which must be replaced. Depending on the application, carbon and silicon content are adjusted to the desired levels, which may be anywhere from 2 to 3.5% and 1 to 3% respectively.

Cast iron's properties are changed by adding various alloying elements, or alloyants. Next to carbon, silicon is the most important alloyant because it forces carbon out of solution. Instead the carbon forms graphite which results in a softer iron, reduces shrinkage, lowers strength, and decreases density. Sulfur, when added, forms iron sulfide, which prevents the formation of graphite and increases hardness.

Cast iron can be welded directly to steel or iron. However, cast iron gives a rough, bubbled weld, and usually need to be expertly ground down.

A rosette is a round, stylized flower design, used extensively in sculptural objects from antiquity. The rosette derives from the natural shape of a rosette in botany, formed by leaves radiating out from the stem of a plant and visible even after the flowers have withered. The formalised flower motif is often in carved in stone or wood to create decorative ornaments for architecture and furniture. A common motif in metalworking, jewelry design and the applied arts at the intersection of two materials, or to form a decorative border.

Rosette decorations have been used for formal military awards. They are also used to decorate musical instruments, such as around the perimeter of sound holes of guitars.

Welding machines are usually classified as constant current (CC) or constant voltage (CV); a constant current machine varies its output voltage to maintain a steady current while a constant voltage machine will fluctuate its output current to maintain a set voltage. Shielded metal arc welding will use a constant current source and gas metal arc welding and flux-cored arc welding typically use constant voltage sources but constant current is also possible with a voltage sensing wire feeder.

The nature of the CV machine is required by gas metal arc welding and flux-cored arc welding because the welder is not able to control the arc length manually. If a welder attempted to use a CV machine to weld with shielded metal arc welding the small fluctuations in the arc distance would cause wide fluctuations in the machine's output. With a CC machine the welder can count on a fixed number of amps reaching the material to be welded regardless of the arc distance but too much distance will cause poor welding.
