What does fabrication mean? Fabrication is the process of constructing products by combining typically standardised parts using one or more individual processes. For example, steel fabrication is the production of metal structures using a range of processes such as cutting, bending and assembling.Cutting, punching, forming, shearing, stamping, welding are common fabrication techniques used to shape, cut, or mold raw metal material into a final product. Fabrication is distinct from other manufacturing processes.There are many types of fabrication techniques where the most common ones are cutting and machining, punching and drilling, straightening, bending and rolling, fitting and reaming, fastening, finishing etc.
