Metal Fabrication

The process of construction of machines and structures from raw materials is known as metal fabrication. Some of the raw materials useful for metal fabrications are plate metal, pre-formed and expanded metal, welding wire, fittings and castings. At the beginning these raw materials need to be cut to the correct size. Tube bending machines and rolling machines are useful in bending and making round portion of metal. Parts are welded and joined together, and then after cooling the machine or structure is usually painted. This final product is inspected before it is shipped off to the client.
