steel
Steel is the most common alloy used in the metal fabrication industry.Common applications include shipbuilding, pipeline transport, mining, aerospace, white goods (e.g. washing machines), heavy equipment such as bulldozers, office furniture, steel wool, tools, and many more. Steel is can be welded with all welding techniques. STICK welding is commonly used with ship building and steel frames in most large buildings. It is the least expensive of all the alloys but can easily oxidize (rust) from condensation. Paint is used to prevent steel from rust but needs to be welded prior to painting. STICK, MIG and TIG all can be used in the weldment of steel. For portabilty reasons STICK is the preferred method with MIG being the next choice. TIG is primarily used only when the weldment of aluminum and other alloys are expected.
